I can only speak for the Quikspins. They are the only way to go in my view. My bow shot just fine before I fletched the spins and the groups just shrank teh frist time out. They are expensive and after reading your questions I'd say you should wait to see the outcome on your bow. As badshotbob said the arrows you have might not even be the proper shafts and spending the money twice isnt a good thing. If it is too long or short of a draw you should look for a means of either ajdusting the draw (this means changing pullys on an older bow) or just find something else to shoot. Having good, tuned equipment is important. Read some of the "I can't find my deer" stories and put two and two together and there just might be a common cause.
