I must be all legs. I'm 6ft 1" but my inseam is 35.2 inches. I have pretty long arms so my torso but be the size of a midget???
I started with 62 (trek's frame) and rode those for a number of years but have recently migrated to a 58 as the ideal geometry. I actually had both sizes at the same time but had the saddle the same height on both bikes and the reach was also the same. The new Prince is even a tad smaller. I enjoy the slightly shorter TT length and reach with smaller frame size.
I think you nailed it when you indicated the availability of all the adjustments. I know I've completed numerous 6-8 hour rides on 58-62 size frames and was comfortable on all sizes-but had them all fitted pretty similarly.
