At higher pressures the slide valves become less efficient and... ergonomic? I lose air when I pull it as a trigger, and I lose air when I push it forward to feed, higher pressure = more air lost. Also, since it gets harder to pull, it throws off my aim because I end up yanking the gun a bit

I got the same problem. i've seen on your later post that you somehow managed to resolve it :
put back the slide valve and its fantastic. Operating at 800 PSI.

what did you change ? :?:

A little complex but you could consider spring-loading the slide valve, so that pulling the trigger releases it...
