Appropriate servo for airframe

I've posted before my intention to scratch build an F3A in about a 90 four cycle size airframe. I thought I'd get an opinion form this group as well as on the other site,

I'm struggling a bit picking servos to use for that airframe. I've never used digital servos before so might give them a try. It is my impression that a digital servo has better holding power than an analog servo. Does that mean I can reduce the torque "slightly" using a digital?

In any case I was thinking elevator and rudder (single servo each) should be somewhere in the 70 to 90 oz range, the ailerons around 40to 50 oz range. The throttle can be about anything small or smaller

What would be a recommendation of a good bang for the buck servo for this application?

Thanks!

Ken
