Don't get too tied up with all the servo marketing stuff unless you are flying very large models in aerobatic competition. For up to 1.00 cu. ins. size models, you can well get by with standard servos in the 42 oz. ranges especially when you use one on each aileron.
Some years ago, when the big powerful servos were flooding the market with a couple more .OZ each few months, a well known giant scale modeler was released from his writing a giant scale column in a magazine not now on the market, simply because he addressed the folly of the advertised servo-craze created by those selling such servos. The mag. publisher rather have those advertisements than an honest column writer. [sm=greedy.gif]

The big boys get the super powerful stuff, then all the me-toos just have to have them. I have a lot of models, mostly semi-scale with one bipe at 101" wingspan. All my servos are analog with less than 75 oz. torque. OTOH I have a number of digital servos that have never been on an airplane, because they came with one specific radio and the me-toos sold them cheap because they "needed - must have" more powerful servos like XXXX uses. Such folly!

I don't care for digital as they mostly idle at about the same mah-draw that an anolog uses while working. Of course if you're into heavy large models doing 3D stuff, the strong digitals are the answer.

Like my grandson that has to have $150.00 sneakers that wear out in short time yet I wear $15 Walmart specials that last for months.
