I'll also note that with dog shifters, those folks that use servos tend to switch to pneumatics as soon as practical. The legal FRC servos tend not to have enough power to shift on the fly, or so I hear (and I've heard it from enough sources to figure there's some truth to it). No comment on the linear servo, though; I don't think anybody's tried it in a competition yet.
