The King is a waste of money; I destroyed mine in about three weeks, and I'm not even that hard on headsets (ex: my Pig lasted me through three different frames over five or six years). The Solid is definitely the way to go; anyone who says otherwise is probably one of those morons that's too stupid to figure out that the collar loosens when you tighten the grub screw, instead of vice-versa.
On a sidenote, I just read the setup right now, and I have this to say: R-E-T-A-R-D-E-D. Namely the reflective vinyl, the 44t sprocket, the Tuff Wheels, and the double-bolt seatpost clamp.
