We create these situations for ourselves (me included), go round in circles and go mad.
My own fault for using Deon Jackson SDTSWS carver as an example and I'm heartened by Chalky & Dave jumping on me (in an internet sense). I'd be all miffed if they hadn't.
I still say it's relatively simple, if you're charging door tax, you're playing original vinyl. If you want to take a chance with carvers, that's up to you but you best understand the guidelines and if in doubt - ovo.
There, subject closed (?)
