Not quite what I was getting at Alex, I can feel the difference between the spec'd speeds on servo, what I was curious about was two servos with the same ratings, one being digital and the not. Digital doesnt effect the specs on the servo, but the rate of transmission from input on the radio to action on the servo is supposed to be increased.

I have no problems paying for speed, there is nothing worse than a slow whimpy servo.

Main question, is 105 good enough or should I look for more? I've found a few nice Airtronics servos as well (758 for instance), not affraid to pay for it. Both servos are priced about the same.
