IMO those arrows are way underspined for your draw wt. The spine on those arrows I believe is about .500. True your arrow length is short but I still think you're too weak. Were you shooting tight groups with these arrows/bow before the "incident"?
Tell you what, I have a dozen of Easton Epic STs 400 with Quick Spin vanes (1/2 doz that I have not shot yet and 1/2 doz that I had used for practice) that are cut to 28". If you send me a pm - I will give you a good deal on them.
