I am shooting GT 5575 XT RT camo 28" arrows with 100gr RM gator XP broadhead pushing 290fps. You can get them cut, and fletched from Mountain archery for around $60 + shipping. Total arrow weight around 395gr. KE is 72llbs, plenty for the Gator XP mechanical. Shot a 8 point last friday @ 20 yards. The arrow completely passed thru both lungs and stuck inthe ground 5" , the deer piled up 30 yards away!
