Im using a 55lb compound bow with a 28 inch draw length.
Currently using 2315 XX75 arrows. For hunting I slap on a muzzy 100 grain.
Is this a good arrow for my setup?
That arrow likely will be a little on the heavy and stiffside for your set-up, and may cost you some speed. Your set-up is really close to mine (27", 55# draw). The recommended arrow for my set-up is a 2115. I couldn't find these ANYWHERE so I went with a little heavier arrow,a 2117 (tipped with 100 grain head) and it shoots GREAT with excellent penetration and accuracy...I would give something a little smaller and lighter than the 2315 a try.
