Custom SkyRay King SRK Driver

As I finished my UF T20 mod, I am looking for a big one to fulfill my flashaholic needs ordered this DX deal. So YES, I’m interested in a descent and powerful driver. I have one consideration though: heat management. This might me a problem with 6 boosted leds.

BTW: I need 4 protected 18650’s for this SRK. What to choose:

1. Sanyo red 2600mAh —> $8,36 /pair
2. Panasonic NCR18650a 3100mAh —> $12,50 /pair

For this goal, I’m leaning towards the cheaper Sanyo’s. Any good reason to go for the Panasonics?
