Nope, I don’t really have that money to spend on something I will never use… 
The only flashlights I own are either EDC, or superthrowers I custom buid.
.
The reason I would never use a GT is because it only has slightly over 1Mcd, and even with modding it would only go to about 2-3Mcd.
On top of that, it uses 18650 batteries while I prefer to use high capacity 3S lipos.
Also the BLF GT doesn’t have as much cooling as my lights do, so I wouldn’t be able to run LEDs at 6A+ while staying at low temps.
Finally, it’s a big and heavy light, and if I need to bring a backpack to carry some non-EDC light I might as well take my OptoFire with me which also fits in my backpack but gets 4.63Mcd.
.
Basically, I would need to buy 18650 batteries, an 18650 charger, and a $111 flashlight, convert all that to CAD and it would end up like $200+ which I would much rather spend on my next project 
.
I don’t have a BLF GT, the light used for this testing was my custom aspheric thrower “OptoFire”.
