My setup bow is a HTX with 28" 70# draw. My current arrow is a gold tip hunter pro 340 spine cut size 28" from throat of nock to tip of insert and overall weight with tip is 401 grains. My question is are these arrows ok? And if they are ok should I get 300 spine arrows in the future? Also would there be any benefit from 300 spine over 340? I have been looking for the answers but figure you guys would know best.
