Thanks to this community and your friendly incite I've been given the skills to throw these together myself. It's not much compared to the amazing work I see out there, but it's really gratifying to put something together and know how the damn things works tops to tails.
It is a S6, I totaly forgot to take it away before I went to do the beamshots lol. I've got Simon's newer 3v 8a buck driver driving a sft40 6500K and with a SMO reflector. It's pretty freaking potent.
Personally I'm really happy that the buck driver's inductor is short enough that it fits in the smaller S6+/S8+ engines. I need to pick up a few of the 8A ones to revamp some triples I have...
