I shoot for Gold Tip and will tell you that I use the Pro 22's for 3D and hunting. Now I'll tell ya about carbon arrows and spine. Carbon works well if too stiff. I shoot those .300 spined arrows at only 53# out of my 3D bow and they bare shaft well out to 30 yards. On the hunting setup at 58# my broadheads fly just fine as far as I choose to shoot them.

Personally I would have gotten XT's and not necessarily Pro series. The XT's are straight to .003 where the Pro's are .001. Then till you cut some of the nock end off and cut them to final length the .003 is going to be more like .002 or even less. Plenty good enough for even the most discriminating target shooters in the world. Why spend the extra money?
