both are fine, if you might shoot at clubs that won't allow all carbon shafts, the A/C Protour would be the obvious choice, but otherwise both arrows are designed to be as accurate (if not more so) than you. I shot a 333 90m distance last weekend with an 8 year old set of Protours that are so worn they have no logos left at all. As long as you look after them, they'll go in the middle (or anywhere else you might point them!)
I know the first series of Protours had a reputation for breaking when shot into straw, I think they made the second series tougher, but I think they still recommend a certain level of penetration from targets to be shot into (though this might only have been for the first series).
