I get the hunters from tm, I think he posts here. He makes them up with the unibushings for the nock, which is real nice and which will save you arrows if you're shooting groups. He weighs and sorts them so they're close in weight and we keep track of that so that we keep the weight consistent. I don't think you're on the border in terms of spine you definitely need the 7595's, it'll only be 20 grains more, and it's a much more durable shaft. Hope this helps.
