I've struggled with the tri-fold knee-board, but primarily because I'm 6'2" and so my knees are right up there beside the stick. When I have the knee-board on, "controls full and free" is a bit marginal, so I just use the board bit and dumped the tri-fold part.
Seriously considering a straight-forward A4 clipboard though - darn sight cheaper than anything with the word "aviation" in it's name too!
