You don't need digital, LOL, no one but the couple dozen top drivers in the world would make any advantage from them(If there was one, there is not). All they really do is suck battery power at an enormous rate.
I like the 925 analog for steering my 950's, there really isn't much point having way more torque than your servo saver has 'give', take the speed with enough torque over mega torque (and mega expense) any day.
