I did assume you were some n00b that I just havnt seen before that was going to blow himself up. But if you think you can use pvc safely than alright do it.
Thanks for your input. I have decided to go ahead with the pvc hybrid, but I will probably not go beyond 2 or 2.5x
I will save that for the metal gun next year.
