Cool, thanks everyone... i'll check around to see if i can find some other threads about this, but from what i gather I'm going to want to stick with the 700c wheels and have no choice really but to find a sloping top tube. Given my torso length i would be looking for a top tube of about 52cm or maybe more. The smallest size of the treks that Patriot posted are "50cm" with 52cm top tubes, and standover heights of 28.4" That will likely be a snug fit under the boys, although it's not like i'll have to worry too much about falling that way.

To be sure though, a sloping top tube is really my only option given my legs vs torso dimensions, correct?
