all stock g7 (polished graphite)
none, some wgp groupies like to rat on SX for some reason
crome ones tarnish
i have one on my e2, it's preety fast. it's not the fastest like the ans, like, you can see the needle jump, but it always recharges fast enough. i shot a steady rope of paint at 19~24 bps, and it keeps up. a lot of kids who own wgp markers think they are better than anyone else, but whatever they have problems, lol. As a person who owns both system x and wgp products and being sponsered by wgp, there is nothing wrong with system x, i get the same performance out off both.
This is a fast recharging reg that is preety comparible to the black magic reg, if you need a fast recharging reg for a sweet gun, this is for you. right now this product is rated 5.9 for some reason, and it definatly dosen't deserve that, so i'll boost it.
