buying 2 flashlights, 1 flood and 1 throw

Hi everyone,
im pretty new to this forum, but have already read some reviews, and i’m especially interested in lights Small sun yz-t08 and Skyray King, about 100€ for both. I already own Xtar b01 with q5 cree, but at the moment isn’t working as it fell to the ground and i havent figured out yet whats wrong.
Anyway, the next question is, where to buy the King so i don’t get a mimic and which would be better, NW or CW?
Now about the batteries: go with these?

If these are really 3100s from panasonic i think it’s a pretty good deal, cuz i need the charger too, only have the MP1 from xtar that i got with my b01.

What u think about upgrading my b01 with a new driver and maybe a XM-L t6 cree, would the body handle more heat?
Please let me know what u think about my plans and what would u do different.
Tnx for any replies :slight_smile:
