I agree a good pad is money well spent. I have one pre-fit Sims which is very good. However most my rifles wear Grind to fit PachmayerDecel, done by my gunsmith. Either are excellent choices IMO and do the job at reducing felt recoil. If you can find a pre-fit to work than go for it, if not talk to gunsmith about putting on a grind to fit. In my area the cost is not much more than the pre-fits you buy from the store.
