I love my .308 CTR, it's one of the most accurate rifles I own (went 2 for 3 on clay pigeons at 700yds on Sunday). That said, it does kick more than a .308 ought to, and I've thought about about giving it the limbsaver treatment like the other Tikkas I've owned. I'm sort of concerned that the cushy pad might mess with consistent shoulder pressure and affect accuracy... Have you seen any change in accuracy since you put the limbsaver on?
You could always try a brake. I know they are loud but if your goal is reduced recoil, there is no doubt they are very effective. I shot a CTR 308 with a APA Little Bastard Brake and it was incredible how much it reduced the recoil. And yes it was loud.
