I never use pitch bend or modulation, but if I were to I'd be happier with the both-in-one joystick my Roland XP-10 uses because of the tendency to return to the neutral position. I also sometimes use my brother's Yamaha CS2X, which has wheels that stay put wherever you leave 'em set, and I don't really like that - simply because I don't like what the controls do to the sound ^_-
