[quote=591789]And my arrows The 340s were 28 1/2 inches long look at you chart right in spec and still wont tune at 70 lb ![/quote] All charts I am aware of indicate that half inch arrows are rounded up to the next inch. In your case it would give you a 29 on the chart, still indicating a 300 spine arrow. Back your poundage off to 60 pounds and shoot the 340's and see how they do. That will tell you if you have a spine issue. As far as the 400's go, you may go ahead and sell them. Too bad you sold your 340's - you are going to need new arrows anyway. I guess you can try that when you get your rig back.
