Which is the better restraint depends on, for me at least, what type of airtime we shall get. For Intamin, you can't get any better than the U bar tbh.. as it is much better than the T bar and still gives a great ejector feeling (the only airtime Intamin is any good at). While 305 will have floater.. most likely judging on the first hill.. the rest will be a mystery. Ejector in the OTSR's is just plain painful.. as the bar in the middle of the thigh does not feel good by any means, although the feeling is incredible.
