SSC P7 driver question

[Lolaralph]

I'm building my first mag mod, a 2 D powered by 2 18650 , I plan to use the britelumen heatsink emitter combo. My question is what emitter bin DSWOJ or DSWOI and what driver. I like the one e-electronics.com has that is specifically for the two 18650. Any advice or suggestions are greatly appreciated
