This offseason I'm trying to figure out the best arrow setup I possibly can for Elk and would appreciate any opinions or thoughts you guys had. I currently shoot FMJ's but have been considering a few other arrows. Does anyone know much about Black Eagles? I want to shoot a fixed blade 125 grain head and would appreciate any thoughts on possible choices. I've heard your FOC % can have a large impact on your arrow penetration, does anyone look for a specific FOC or have any tips or advice when building killer arrows?
