I'm 5'11" on a good day, 5'10" on a bad and am not even close to skinny. I have been able to go on everything. Crush was the only one I had any discomfort on - but I think that had more to do with the large meal and long line than the seat.
Hiya, can you remember what the restraints are, are they similar to rock n roller coaster and stop when they get to you or do they have an automatic stop point?
