I mounted a Zeiss Conquest 4-14x44 to a Sadlak mount with a pair of high (.980") QRW rings and like Rich have been pretty happy with them.I've been using the Leupold QRW rings on a Sadlak mount for 5 or 6 years now and I'm very happy with that set-up.
I can remove the scope to shoot in an iron sights only match, then put it back on and be within 1 MOA.
I have the some concern about Leupold QRWs, but I've also had the same results (no scratches so far), I just carefully use them. They're also cost effective. I like them.The only thing I don't like about them is that the upper strap of the ring is over 180 degrees so you have to sort of spring them onto the scope. I haven't scratched a scope yet but always worry about it.
