Interesting update on "crappy" repro fan shrouds

I'm thinking about purchasing a re-pop 614 shroud for my 67 Barracuda. Since this thread is a few months old, I wondered of anyone could give an update on the performance of the 3rd generation of plastic.

Are the new shrouds more heat resistant? I'd sure hate to throw away that much money on something that warps the first few times I use it. If anyone having the problems mentioned in this thread can give an update, it would be much appreciated.
