Hi Dale, yes you and your Texas Poker is a big inspiration in my pursuit to build something that small and powerful, + i just today found djozz second mod of the “LZZ-06” :LZZ-06 mod#2: XM-L2 T6 3C, BLF-tiny12 driver+FET, Efest 10440 V2 ***27 lumen/gram !!***
And i had already ordered one, nice looks like the possible host i wanted 
Besides the BLFTiny10-12DD i am also considering trying a QTC direct drive in a twisty to get some control and usable lower output, they should manage up to 10A.
I wonder i anyone have tried one in a 18650 twisty………
