The Carbon Express Maxima or the Easton st Axis are good choices in a carbon shaft with tight tolerances, but if you already have two doz. of the epics I wouldn't be afraid to use them for deer!
As I said earlier I shoot them at ground hogs tipped with 100gr. muzzy's and they fly very true,I would also use them for deer but I have a doz. of the Maxima's, but if I didn't I would use the Epic's!
Shoot them and see how well they fly you may be surprised! Good luck
