I’m in, thanks for the GAW gchart! 
I believe my 1st mod would be my favorite (as everyone remembers his first time :heart_eyes: )… but I’ve never made a flashlight mod myself. 
Many mods I’ve seen @BLF have impressed me, but it’s CRX - 4th BLF/ Old Lumens Scratch Made Light Contest - Handmade that I like most, because of CRX’s unique imagination, skills and materials he used.
If it doesn’t count as a mod (as it’s made of scratch), then I won’t pick one of the great flashlight mods I’ve seen, but CRX’s How a Zippo Armor lighter should have been made. As a flashaholic smoker I am 
, I found it very good idea and I really enjoyed reading something other than flashlight mods @BLF.
