Well I decided on the 7.3...Got the rack and fenders,bar ends and an arkel rack pack installed(because it was my mode of transportation home). I also took a few measurements of my own to compare to what I was used to that don't show in the geometry on the site and the only real difference was the floor to hand grip. The one I'd been riding was about 2" higher. After getting dropped off from work today at the bike shop I only had to ride about 4 miles home but the first thing I noticed besides the height of the bars was the difference between 26" and 700 wheels...Time will tell...
