What cells do you use in your Trustfire X6?

As I sadly found out today (and posted in another thread) Panasonic 3400 mAh protected cells wont fit in a Trustfire X6 without modding the light in some way. I am currently using protected Trustfire flames in mine, but I am a little weary of using them since this light draws so much current. I am curious what other people on here use with their X6’s.

I use either protected 2600 mah Xtars, unprotected 2900 mah NCR18650, or salvaged cells.

According to HKJ, the 3400 protected Panasonics are some of the longest he’s come accross.

HI-MAX 2600 mah

I ordered some 2600 mAh protected Sanyo’s from fasttech.com. Hopefully they fit.
