I've been practically dying waiting for this to come out. I personally don't mind a tank at all. the weight difference it makes in my rig is nothing, and would allow for adjustable fps at the turn of a nob on the regulator on your tank.

There may be more lap sitting, and I might answer more of your questions with a story, but mostly my mustache tells people that there is a 90 percent chance that I am poorly educated, that I keep up scale porn out in the open, and that I listen to the Little River band with large headphones.
