Going Digital
Digitals center 3 to 5 times more per second than an analog, they are more prescise, and some like the Hitecs are programmable. You can get analog servos that have more tourqe than some digitals. Digital doesnt always mean more power, just most manufacturers only make the really powerful ones in digital. The programmable ones are really great though. The Hitecs are one example, and I think the Multiplex ones are programmable too. With the Hitecs, you can change the ATV, failsafe position, subtrim, transit speed, and some other things.
