The arrows could be a little firm for the bow if you were drawing 28" and cut your arrows to 29". If you're drawing 30" and cutting your arrows to 31", they may well be too weak for your bow, because of the extra length. If you're using 125 grain points, try using 100 grain points. 100 grain points would probably be a better match for the light cedar arrows you're probably using in that bow anyway.
