hi john, i am pretty new to the cc game,its not that i yearn for a huge powerful machine but everybody goes on about a min 135-150 psi and 2x3 stage vacs and to be honest i,m constantly worrying about wickback,shrinkage etc and i think i,m wasting a lot of time doing too many dry strokes, i do have a rotary and a crb machine so i would like to look into utilising them as much as i can...thanks
