RE: Diamond and PSE
I really, really enjoy shooting my Liberty. It's the "back up" to my Marquis, but honestly it is working hard to win my heart. I don't really care for the Black Ice - but that's me, it's too short.
Another big plus for the Liberty is the price - to obtain that quality at $550 TYD, you can afford to spend more for your sight and rest (and a Mean V suppressor, of course!)
