Guys again, I am NOT asking whether I can lube the UP valve or not. The problem is that there is ALREADY tons of BVM O-Ring Lube in my retract and door cylinders and airlines (my bad, but there was no other way I knew of to lubricate the cylinders and cure their leaks, and I did NOT know at the time I did it that there would be a compatibility issue). My question now is should I carry on with the UP2+UP4 combo or have I doomed myself to switching to another system?

In other words, how big a concern is it? And have people been using this combo without hassles regardless? I think I may have screwed myself and now have to choose between an EV5U or my Details4Scale Electronic sequencer and a whole bunch of servos and BVM Hi-Flow valves.
