I also did the early buy 100 rolls of which we ran out of a long time ago and stopped using. My guys said the 1" pipe seemed to "snap" sometimes instead of a smooth cut all the way through and the 3/4" rolls were not consistant ID's. Anyway we did two jobs that we ran a poly live leg and they both sprouted tiny pinhole leaks all over. I fixed it by putting in master valves but I was not happy. That never happend with oil creek and we will not use Poly Star again.
