Greenie, I love man, but honestly, how much "real world" CCing experience do you have?
Did you work a year as Lisa's chimp before you kilt Moby?
The bayco i tried would run up to 15 then would cycle open and drop to 13.
That's not good enough for me.
I get more consistent vac with my stock valve.
If doesn't fluctuate a half HG when cycling.
Maybe your helping the guys who soak carpets, can't clean berbers, run live reels, or don't know piling their vac hoses in a jumbled mess robs them of air flow, but I'm not one of them.
I'll try anything, I just don't see all of it as "all that"
..L.T.A.
