First, the negative: I must have missed where it said in the description of the 350 lb bumper set that the 45s would be coming several weeks later. That was listed in the paperwork once the initial batch came in. I chose the virgin rubber set because I wanted the least bounce with the least noise for the best value for use indoors and my research led me to Vulcan. So far, I am pleased but I have only had them a couple of weeks and I don't do a lot of dropping period - and almost never from above the waist. I also picked up the 15 lb black V-lock change plates. Pricey per pound but they fit snugly on the bar and work well for my needs.
