Yeah, give it a go.
When filling, air up the EVOL First, there is a small floating piston inside and if you don't, this piston will be in the wrong position. If you are unsure, simply let the air out of main chamber, fill up EVOL and depressurize the main chamber again, this will insure the floating piston is in the correct position, you can even feel it move to the bottom position when you do it if you know what to feel for. NOW set EVOL pressure, then MAIN. Just sayin...
