Peak Moment to Date: Showed off a rich, powerful tone on Sheryl Crow's ''If It Makes You Happy'' while strumming the guitar and breaking out the harmonica.

Achilles' Heel?: Certain segments of Idol fans are notoriously tough on rocker chicks, women with tattoos, and single mothers.

Peak Moment to Date: His strangely sexy audition to ''Let's Get It On'' has already scored him a fanbase called ''Grady's Ladies,'' and his retro-cool vibe should be fun to watch juxtaposed with Idol's cheesy machinery.

Achilles' Heel?: Producers pretty much ignored him throughout Hollywood Week. WTF? (Why the face?)

Peak Moment to Date: Served up a sexy ''Chain of Fools'' in an Idol season 9 promo.

Achilles' Heel?: Aside from a four-second solo singing ''Irreplaceable'' (with Ashley Rodriguez and Charity Vance) during group rounds, she's been season 9's invisible woman.

Peak Moment to Date: Improved on Miley Cyrus' original when he performed ''The Climb'' in Orlando, and his ''yes, ma'am'' charms will play well with fans of squishy teenage contestants.

Achilles' Heel?: Flubbed his lyrics not once, but twice, after scoring a Golden Ticket; at the tender age of 16, we're not sure he's ready for this jelly.

Peak Moment to Date: Got dubbed an early front-runner thanks to a solid cover of ''If I Ain't Got You'' during Idol's season 9 premiere.

Achilles' Heel?: Has the voice and the look, but hasn't yet shown the inventiveness it takes to win the competition in a post-David Cook era.

Peak Moment to Date: Of the umpteen renditions of ''I'm Yours'' during the Hollywood rounds, Todrick's showy, inventive take (featuring flourishes of falsetto and growl) was the best.

Achilles' Heel?: Most of his interview footage — getting snippy as part of ''Destiny's Wild,'' macking on bikini babes while lounging poolside — has been Rated A...for Annoying!

Peak Moment to Date: Delivered a knockout, folksy twist on ''American Boy'' during Day One of Hollywood Week, but that sumptuous audition snippet to ''House of the Rising Sun'' remains her crowning achievement.

Achilles' Heel?: Final Hell Week performance of Taylor Swift's ''Love Story'' was kind of a mess, with Janell admitting she couldn't handle the pressure. Will she crack when she has to perform live for 25 million people?

Peak Moment to Date: The rich, sexy baritone he showed off on Blood Sweat and Tears' ''I Love You More Than You'll Ever Know'' left Shania Twain drooling like a Pavlovian canine.

Achilles' Heel?: Lone Hollywood Week footage included John's voiceover expressing vague disappointment with his performance.

Peak Moment to Date: Thirty-second snippet of Hollywood Week solo on ''Living for the City'' proved she's got as much vocal horsepower as any woman in the competition.

Achilles' Heel?: Siobhan's frocks have veered from granny garish (a heavy white-lace top Ellen described as too old) to gimmicky '80s kitsch (newsflash! only Dancing With the Stars' Edyta Sliwinska is allowed to wear legwarmers in prime time!).

Peak Moment to Date: Impressive mop of hair and last-minute semifinal substitution for disqualified Chris Golightly are his current claims to fame.

Achilles' Heel?: His butchery of David Cook's ''Come Back to Me'' will not please season 7 loyalists.

Peak Moment to Date: A top 50 contestant in season 8, her ''Over the Rainbow'' was a definite highlight of the talent-packed ''Road to Hollywood'' audition episode.

Achilles' Heel?: Her subtle style — that Hollywood Week rendition of ''What a Wonderful World'' occasionally dissipated to a whisper — might work against her when she's backed by Idol's ''Bandzilla.''

Peak Moment to Date: Made a big splash taking off his shirt for Kara, but it was a bluesy ''I Don't Need No Doctor'' on Day 1 of Hollywood Week that proved he's got a legit shot at the season 9 crown.

Achilles' Heel?: He can sing for sure, but both his audition and his Hell Week cover of ''Bubbly'' betrayed a lackluster stage presence that could get exacerbated on Idol's big stage.

Peak Moment to Date: Wasn't shown during the audition rounds, but her nuanced, acoustic cover of ''Lullaby of Birdland'' on Day One of Hollywood Week turned her into an instant contender.

Achilles' Heel?: Pushed her vocals too hard on Hall and Oates's ''Rich Girl'' for her final Hell Week performance; needs to remember that the show has evolved past its former ''bigger is always better'' ways.

Peak Moment to Date: Personal trainer has the jauntiest personality of the season 9 crop — loved that shuffle-y dance after he cracked the top 24 — and scored plenty of screentime after his wife gave birth during his Hollywood run.

Achilles' Heel?: ''She's at eight centimeters!'' Seriously, dude? Also, his acoustic version of ''I'm Yours'' threw up a red flag about problems with breath support and pitch.

Peak Moment to Date: It was almost impossible not to be charmed by her zippy audition to Carrie Underwood's ''Last Name.''

Achilles' Heel?: It was almost impossible not to be appalled by her botched lyrics to ''Sweet Escape'' and botched notes on ''I'm Yours'' during Hell Week. Needs to pull it together — pronto! — or this adorable kid will be the first one swept overboard this season.

Peak Moment to Date: Brief audition snippet of ''Ain't No Sunshine'' (which was presented side-by-side with Crystal Bowersox's ''Piece of My Heart'') showcased a hot, gruff vocal.

Achilles' Heel?: Botched the intro to the chorus of ''You Found Me'' in his final performance — and that lackluster rust cap and blue t-shirt weren't exactly screaming ''music superstar,'' either.

Peak Moment to Date: As Simon sent her through to the top 24, he told Paige she was a better vocalist than she realized.

Achilles' Heel?: Other than a brief flash of her doing backup vocals on Neapolitan's a capella ''Bad Romance'' (in which she didn't even get identified!) Paige has been largely absent from the season 9 proceedings. Do the producers realize she is auditioning for Idol, not Without a Trace?

Peak Moment to Date: His acoustic twist on Paula Abdul's ''Straight Up'' was one of the best Hollywood Week performances in Idol's nine-season history.

Achilles' Heel?: It's always dangerous to peak too early in the competition; Idol voters love to see growth as much (if not a bit more) than consistent excellence.

Peak Moment to Date: Wowed the judges in Hollywood with a gorgeous rendition of the Kara DioGuardi-penned ''Terrified.''

Achilles' Heel?: Near-constant crying and relentless references to deceased friend could quickly go from affecting to annoying.

Peak Moment to Date: Didn't hit any bum notes during a 10-second, blink-and-miss cover of ''Man in the Mirror'' during Hell Week.

Achilles' Heel?: Near total airtime shut-out makes him potential semifinal cannon fodder, unless, as Randy might say, he ''blows it out the box, dude!''

Peak Moment to Date: Her Boston audition performance of ''At Last'' was powerful and in-tune, and possessed an elegance and depth impressive for so young a vocalist.

Achilles' Heel?: The show's relentless mentions of her Alzheimer's-afflicted grandmother have threatened to overshadow Katie's vocal talents. J'enough!

Peak Moment to Date: Survived working with she-beast Mary Powers performing Fleetwood Mac's ''Dreams'' in the group round; name similarity to a rather popular season 8 finalist might win him a few votes, too?

Achilles' Heel?: His ukelele showed more charisma than he did during his paint-by-numbers rendition of Jason Mraz's ''I'm Yours.''

Peak Moment to Date: Shania Twain said her audition to ''Syrup and Honey'' showcased the kind of voice that could make a hit record.

Achilles' Heel?: Simon and Ellen both criticized Katelyn's Hollywood Week performances; is it possible she's being pegged for the Kristy Lee Cook/Haley Scarnato ''pretty girl punching-bag'' slot?

Peak Moment to Date: His audition, a soulful and sweet reworking of Joan Osborne's ''One of Us,'' was intriguing and unexpected.

Achilles' Heel?: Has a tendency to indulge in showboat-y vocals; that glory note in ''Carry On Wayward Son'' during the group round was as subtle (and enjoyable) as a kick to the groin.
