fyi - gas is my preferred dedoming method - 100% with it, lots of XM-L2's done, some XP-G2's. My thread here: https://budgetlightforum.com/t/-/17374
Also, the resistor mods work fantastically with this TN31 driver! Bridging the resistors have seen throw measurements made as high as 490 kcd, de-domed. If you want to go milder, than adding resistors will do the trick, just compute the conversion from ohm to amps, and add resistors accordingly.
