The stock on the S2 is by far and away better than the usual synthetics more commonly found 700's etc. The fit and finish is near perfect on all of the ones I have handled. There is no "up pressure"—to hell with "up pressure"—the stock fits like the proverbial glove. The point is to let it cool between shots so that stress/memory in a barrel is not changing your POI through contact with the stock.
And I firmly believe that slowing down produces noticeably smaller groups, saves you erosion, anxiety, and money. You will live longer and eventually die with more teeth and hair.
