Sorry to pick your post apart but as far as your torque explanation goes. Torque has nothing to do with holding power in a servo they are considered 2 separate components. Torque rating in a servo is the power behind the swing all anolog servos dont reach full torque until they are 20% into the throw of the swing. Digital servos have it from the get go there percision is from their pulse 5 times faster than an anolog servo 60 vs 300. Now as for holding power that comes into play as the gear set composote. Karbonite, plastic or MG and the gear train layout all have to do with how well the servo will hold at any deflection. As far as deadband goes there is 0 in digitals that is why they always make a humming noise they are constantly maintaing a 0 dead band. The hum is normal so is more usage out of your battery. If you choose to go digital consider a 6V battery first and nothing lower than 1500 MAH. Anolog servos do give the most sloppy deadband and along with chatter MG servos have their fair share too, however its a compromise when you need more than 80 oz of torque. There is no karbonite servo out yet with a higher torque rating than 76oz I think.
