If you're going to get new arrows anyway I'd suggest a step up to 7595 spine.
As would I. And I'd be willing to bet you see a remarkable difference. Not only by getting spined better but new carbons always shoot a lot better than old beat up carbons.
Ditto and the gt's are IMO a weak arrow given to exploding. Had a store tell me this about the xt's a few years ago.
