Hey all I was owndering can someone tell what is teh differance between the 85g and the 125g wieght broadhead? I am looking to buy new ones I am shooting 70#s and a 31" arrow, I am sure the more they weigh the harder the impact does it matter the weight of your draw to the weight of the broad heads you shoot, kinda of a simple question any info would be great thanks

40 grains is the difference. It could effect the tuning of your bow, as far as impact force I would say you probably won't notice a significant increase in kinetic energy with 45 grains added. There are some great 100 grain broadheads out there and probably a little more selection than 85 grainand you will only be adding 15 grains of weight to the tip of your arrow.

85 grain points are lighter so they will fly faster but with the 125 grain it will fly a little slower but have more momentum behind the impact

It will effect the spine of your arrow and get you more FOCbut most of allit will effectthe tuning of the bow.

whatever weight of your feild tips you use is the weight you should go with on broadheads imo. if you shoot 100gr. field tips then you shood shoot 100gr. broadheads.
