I recently received the F3 after 22 years of using an Invacare Arrow. Needless to say the adjustment from rear- to front-wheel drive took some time, but the front-wheel is so much more maneuverable. I am 6'4", so have been used to needing a lot of space to turn around. The F3 allows me to turn around in such tighter spaces. And I've been very impressed with the suspension.
