going brushless (savage x 4.6)

Ok great,i will probably go with the 10XL,i was originally thinking of using the Zippy 3s 5000mah 25c packs,will their be much difference in preformance/heating over the 3000mah 20c packs?
Also for gearing,i realise you recomend around 15t pinion,though the CC2200 has a hgigher KV rating,and is geared higher(25t on 6s),are you sure i will get enough top end with a 15t Pinion?
