Ok...i have a Hoyt Lazertec, set at 55 Lbs with a 30 inch draw.

Ive been reading all kinds of post on arrow FOC and spine and weight and all this other crap. When i first got my bow i went out and bought Easton ST Epic arrows and shot slik tip field points and Muzzy MX-4 broadheads and i killed a deer no problem. Now during the off-season i started reading all this stuff.....is my set up ok? I mean i never cared about spine and FOC and my bow shoot pretty straight....is there anything i should be concerened about?
