I just purchased an RT. It is important to sit on them and try them out. I decided I liked the floorboard models. I also found out that at 6'0 29 inseam, that I was a bit tight on legroom as I am not able to move my legs out further and further to get additional legroom. I settled on the RT as it was the best compromise if I wanted to take my wife with. I think for the taller people, the F3T is a great choice as the foot position is adaptable and the seat height is much lower. Definitely sit on both before choosing. It is cheaper to buy the right machine the first time around!!
