The ding in the flight rail on my impact has been driving me crazy the last two weeks. The arrows simply don't stay flush on the uneven deck. I can't file the imperfection away and I don't want to keep wondering if the bow will shoot better without this problem. I called Darton on Friday and got a RA #. I'm having a new rail installed so I can finally stop fretting over it. It'll set me back $265.00 (shipping included) but I think it's worth it.
