I always thought a stiffer spine was going to be best for a heavy lb bow , but I noticed that Cameron Haines shoots a 400 spine fmj with his 80 lb hoyt.I shoot 340 fmj's out of a 70 lb elite ,but would love to lose some weight by going down to 400's .

watch some videos on shattering carbon arrows before you decide deviate from specs.he probably doesn't shoot his arrows much before they are replaced with new.... i shoot beman 340 on my 80 pound bow because that's what the specs call for and i get close to 312 fps. with them
you do realize what the 340 and 400 and 500 meen right? and please im not being a smart alek
He shoots a short arrow, which stiffens up your spine. A 400 spine arrow Is only 400 at I believe 29", any shorter and the arrow stiffens up. These arent exact numbers but say you cut a 400 spine arrow to 25", it now will be as stiff as a 300 spine arrow at 28". Take a piece of steel the size of a pencil and try to bend it, you cant, very stiff. Now take that same piece of steel at 3 feet and its much easier to bend. Same idea.This is why he shoots a 400 out of an 80 lb bow. Plus, he doesnt seem to be having any problems to me.
