I believe every hybrid made out of PVC has exploded, even though it was rated to the pressure, it was the pressure SPIKE that did them in.

The chances of failing may be more or less equal for a DWV combustion and a PN16 hybrid, but WHEN it fails, the hybrid explodes somewhat more violently.
You will not want to be near it when it fails unless you have the wish of getting sharp pieces of material in your body that do not appear on Rontgen pictures and thus cannot be operatively removed...


So the chances of failing may be equal, but the result isnt.

Ooh, that's up for debate now. Is there any rule that says a more powerful cannon is more fun?
I don't think so. I've had great fun with basic combustions.

Also, there aren't a lot of handheld hybrids, and I prefer handheld cannons for the enjoyment of shooting. Not much fun setting something up, bolting the cannon down, then retreating to a safe distance and pressing a button, is there?

EDIT: Unexpected number 7.

That's precisely what I end up doing most of the time, and you're completely right. If I'm looking to have fun spudding, I go get my old 1.5" bore spray'n'pray and a bag of potatos, not my monstrous 30x hybrid and some slugs that took 30+ minutes each to make.

yeh, i think mate, that if your willing to risk life and limb for 40 dollars (the difference betweeen the steel and pvc) then either your life sucks or your a retard. pvc is fine for combustions, but i personally, and as do a lot of the others here, wouldnt make one out of pvc, no matter what its rating is.

im sorry if i seem to be coming across as a rude asshole or something, but i dont want to read up on here about you dying, or being hurt.
