questions about arrowheads.

I use a 2 bladed 160 ace sharpened with a file to a wire edge, no problems, as has been said here and many times before, shot placement is the key. Most any sharp broad head that flies well will do fine. I have used 2/3/4 bladed heads all with good success , I just like the Ace because it is easy to sharpen and keep sharp and flies well.

so what i should do is find a point that flies well with my bow? i plan on using my ELB for hunting this season so i made the assumption the bodkin three blades would fly well.

Practice! Practice! Practice! And evaluate every shot!  Also, have your broad heads razor sharp, be ready for Murphy's Law, which is governed by Mc Connell's Theorm - Murphy is an optimist!  I am the least qualified as a bowhunter, but you fight like you train, and hunt like you practice. As GunDoc and others say, Shot placement fills the pot!  As an HE instructor, I teach shot placement and practice with your hunting equipment until you are proficient!  The kill zone on deer is about 8" +/-! Regardless of weapon or range.

The same and more attention should be made to how well the shaft flies.A person wants it leaving like a dart just seeing the back end of the shaft at a 20 yard shot.This helps penetration as well.
