WDP Mini reg, vert MAx Flo, ANS in line, Sidewinder, Vigilante
2k Dark Angel, DEZigns Bolt, Dye Stickies, Total Freak, MacDev Gladiator inline reg, quick disconnect, then my Dyna Flow
Everything. I love this reg. It's almost as small as the WDP Mini Reg but far supirior. It has the highest flow and very very consistant. MacDev has really proven themselves this time. I get no more shoot down, my veloctiy is now +/- 4 on a BAD day. The Gladiator can handle the pressure clime that is caused by the Dyna Flows design. It wont budge at all even if the output pressure rises 300psi. When I get low on air, nothing happens, no spikes, no nothing. It came with, in my opinion, a very good manual. It goes over how to take it apart and put it back togather, brief trouble shooting guide, maintence, etc. The price is very reasonable too. At $70, almost half the price of the ANS in line that is very restrictive and less than half the price of a max flo in line, you get a reg that can beat them all.
My only complaint is the velocity adjustment screw. If you stick your wrench in too far, like I did my first time, you must dissasemble the hole reg to get the velocity ball back in position, and you must be very careful not to scratch the piston in the process.
