kamagong,
I think that you will enjoy the G2Z also, when you finally get one. I actually prefer it to the Z2, mainly because of the fact that it does not transfer cold to the hands the way that aluminum does, and the way that the nitrolon feels on the inside edges of my fingers when held in a cigar grip. Hard to describe that tactile sensation exactly, but I like it better. Nitroz did a fantastic job on a "G3Z" that he made for me, also. He does wonderful work.
