heh... yeah, that's sounds like me too. 5'10" 150... BB...
anywho, my car came with a 15" LaCarre leather wrapped wheel. Has a nice feel to it; nice and meatie. Unfortunately, the size (which I always thought look disproportionately large) gives me minor interfearance while driving. My thigh sometimes hits the bottom of the wheel when I "heel-toe". Getting in and out isn't too bad, IMO, but I can certianly see it being a bit easier with a slightly smaller wheel.
A 14" wheel is on my "Iwanna" list, but it's pretty far down; have other things that need tending to to make the car more mechanically and emissions sound.
