I've got one that's only a few years old, and frankly, I like the way it handles better than the older ones I've played with.
So, my suggestion, is find some and do your own comparision. Mine, after getting the trigger cleaned up, breaks at about 3 3/4's of a lb. and is very consistant.
Five shots in an inch with peep sights at 50 yds. with WW Power Points and CCI Velocitors. 5/8 th's with RWS Sub Sonic HP's. E
