If a bowhunter is setting for just speed and flat trajectory, they are selling their performance short because the arrow eventually gets there and a bowhunter want and should expect a pass through regardless of the species and the shot angle or bones hit. A bowhunter that is properly set up knows that he must reach the vitals from all shot angles so if readers here are interested in setting themselves up for success (the pass through shot). You will want to boost your total arrow weight.
To further boost the odds of a pass through, you will want to select a quality fixed blade head so you dont lose energy to blades you hope will deploy.
