Servos and power system for XL3200?

The XL3200 from NSP is a 122" electric sailplane with a predicted flying weight of 72 oz. It has a beautiful built-up wing with flaps and ailerons. I have purchased the following power and radio equipment:

Mega 10 FAI SP motor (direct drive) (72 oz. thrust, 77+ amps)
A-120 speed control (80 amps) from Diversity Model Aircraft
10 Cell 2400 mAh battery from Diversity Model Aircraft
Hitec HS300 servos for elevator and rudder
Hitec 225MG metal-geared servos for flaps
Hitec Eclipse 7 with Supreme 8-channel receiver and 600 mAh receiver battery

I still haven't purchased servos for the ailerons so I'm looking for suggestions. I'm also looking for input on the suitability of the equipment I've purchased so far. Keep in mind my main goal is to end up with a thermal sailplane that is as light as possible but still gives me 2-3 decent (not vertical!) climbs to thermal altitude. I'm wondering if the power setup might be a little overkill especially since the motor weighs over 15 ounces. Seems like I could use a smaller motor battery too. Since my focus is on relatively gentle thermal flying I'm wondering if the 225Mg servos are overkill for the flaps.

I've only been flying electrics for a few months (Aspire EP) so I appreciate your feedback!
