i bought a gforce frame and the guy said either an rt or ult on off would be better for it. i unfortunately deleted his pm. could somebody confirm which is best?
thanks

RT ALWAYS for a pneumag.
In many cases the ULT does not have sufficient return force. I have never had any luck getting the ULTs to work in pneumags.
I'm in no way arguing, but how does that ^^^ make sense? In a Pneumag, the on/off whether ULT or RT is only returning the sear vs returning the sear and trigger on a strictly Mech set up isn't it? I only tried a ULT on a pneud classic which was an epic fail, but assumed it was due to it being a Classic vs RT/X valve. I mean the sear in a Pneu doesn't push the ram back does it?
I was going to leave this as good enough.^
Pneumags are a bit chuffy in the first place. As they get up to speed, the trigger release gets critical as the ram may not snap back fast enough. An RT on/off will help stuff the ram back, whereas a ULT will play along and try to hangup.
To make one work, you need to tune the ULT, and a qev might help, which is something that we've bypassed with the RT on/off. If you run lower LPR pressure, make sure your reg has good response at that setting ( like a micro rock).. I had a tickler that wouldn't work well at low pressure, so i got nothing from using a ULT. Also, light pressures slow the return of the fabco 3-way. When you can slap together and tune a pneumag with a ULT and a new level 10 bolt all at once, you have certainly passed a test.
It can be done, but it's not worth much and adds unnecessary complexity.

It's one of those things, like the ULT in the classic, just say "no".

Excellent reply, and thank you!
thanks all.
I have a M90 pneumag set-up by Tuna, and it works great with a classic valve with the classic on\off. I've spent hours doing trail and error with all my valves and on\offs.
