I have the 2.0 Pro, with a xonik frame. It really depends on you though, nut the 2.0 Pro is much nices for me. The milling is a bit different, and mine came with a twist lock feed neck standard. also the Xonik Frame & Solinoid matches the millind and color of the marker. AS if it was on there standard.
My marker is a black to Grey fade. And its really a sweet marker. Does about 14bps with eyes on, and 18bps with eyes off.
