Buck Magnet,
I shot the Xt's for 3 years, loved them. Last year, I got the 3D Pro's, figuring it may help tighten up my shots for 3D and of course, the kind of targets that bleed. I really like them. Do I shoot well enough to tell a major difference, I am not sure, but I really like the arrows, and I think confidence is a major part of archery. I did get the 7595 spine, as I was wanting to go for a bit heavier arrow. I shot 125 gr Stingers this year and they flew beautifully from my bow. I have them cut at 29" and my bow draws about 64#'s. May not be the ideal spine, but I was shaving fletches at 30 yards, can't complain about that, except it is a pain to fletch more at hunting camp.
For the money, I think they are great arrows. Tough as nails and straight.
