Pat, no doubt QC can be an issue, but that's never the point of most of the anti-Peterson crowd.
I'll give an example. I own a pair of Sanuk Flip Flops that blew out after wearing them for two weeks. I called the customer support, explained the problem and was sent a new pair. Was it a pain in the ass....kinda...was it the end of the world....no. Do I still buy Sanuk shoes....absolutely.
I'm not singling you out, but everytime a Peterson pipe thread comes up someone comments about a pipe they bought that they had QC issues with.
I bought two savinellis that had issues. One of them was purchased from SPC. How did it get past them?
Stuff happens. It gets infuriating, but it happens.
Oh well, the day is new. It's time to enjoy some 20 year old Virgina Woods in a Patent Peterson.
