Which LSD NiMH AA's should I get for a Zebralight H502?

I have a Zebralight H502 headlamp which is a single XM-L powered by a single AA battery. I’m not sure what the draw is on the battery, but I can tell you the XM-L puts out 260 lumens on high with a Sanyo Eneloop according to their website.

If money is not an object, what would be the best LSD NiMH batteries for this light? Sanyo XX Eneloop’s or the regular ones? Tenergy Centura? Maha Imedion?

I tried to read the NiMH comparisons on the other forum and its just info overload with no conclusions :~

Thanks!
