I have the 331 with a sword twilight hunter,s-coil stab,wb deluxe and could not be happier.For a hunting bow I don't see how you could beat it.This bow has given me less tuning problems than any bow I've ever owned.It flat shoots.I shot it about 100 times,put a twist in the string to time the cam and your done!I've shot this bow hundreds of times and nothing has moved yet.My peep lines up EVERY time and it's a tack driver with fp's or bh's.I've owned several bows over the years and none of them stack up to to this ross.I suspect the premium grade strings are a big part of this but nonetheless,it's a great deal for the money when you consider what some of the "other guys" are charging for bows that have inferior standard equipment compared to the ross line.
