I'm one of the guys that have had problems with the Talleys and I won't use them again. Two primary problems I've had... They aren't round, and are prone to cause ring marks on your scope tubes (or even cause tubes to become out of round). I've also had them move around on the receiver which obviously caused major problems holding zero.
I'm not judging people that like and use them. Just stating my experience. I now use almost all pic rails, and Seekins rings. Another option for a ring that's similar to the Talley one-piece is the Hawkins precision one-piece rings. These are expense, but if you compare a set to the Talleys in your hand you'll see why.
I spend WAY too much on hunting trips, vacation time, and shooting equipment to save money on scope rings. Just my opinion.
