Ampa, personally I flew the 9550's and at the end of the year, they did start to get a little sloppy. I know a lot of guys are running 9151's on ailerons. I've been running the 9154's, but am seriously considering going to the 9151's for next year. 9650's are great little servos and you'll have no problems running them on elevators halves. They are going in my Black Magic stuff.
