I stopped by to talk to Bill [Alleghney Mtn Bows]yesterday to see about getting a spare pair of limbs for one of my bows. Boy am I glad I waited. He's doing a new construction design and the ones I checked out were really smooth and even quicker. Bill says he's getting as much as 5-7 fps more with the same weights. Now to decide if I want the same weights or what as bows are really stable and with the faster speeds maybe I could go a little lighter and same my back[okd is getting to me]......Those of you who shoot his stuff should check it out.
