Acebeam K40L led pick dilemma

After almost 4 years since my first K40 buy (it was supbeam then), I bought a K40L. I plan to mod it. My dilemma is using xp-l2 hd or dedome an xpl? I know the K40 reflector has some artifacts with dedomed xpls. Also has anyone experience with resistors stacking in this driver?
