Stockade does excellent work- have dealt with them a few times and have always been very happy. That being said their bolt timing and trueing is done 100% from an accuracy standpoint, they don't claim a major decrease in bolt lift effort. If that is your primary concern SSS may be the way to go. Something else to consider is that actions tend to lighten up with use. My rblp pta smoothed up nicely after a few hundred rounds.
