which one felt best to YOU? which one was the most comfortable? you can compare the component group on the bikes. if they are all the same or closely comparable, then i would go with which ever one has the most comfortable fit, that you can afford.

i am 32 years old and have not bought a fs bike yet. i ride regularly on the trails around here and the ht suits all of them fine. i haven't ventured away from here really to tell you that a fs frame is necessary for the extra money. just a luxury at this point, not a necessity.
