I don't have R/GTs, but I'm on my 3rd or 4th Warrior set and over a little bit of time they've all softened up quite a bit.
For comparison, I've kept choosing them over Optiks with an FLX core, Vapor 2X pros, Premiers, and a couple other sets. The only ones that I really considered was a Gnetik 3 set, only problem was the sizing wasn't quite right.
I don't think anything made today will play much like a traditional old school pad unless you get a bespoke old school pad made.
