I read a great article about penetration, and how broadhead design effects the outcome. The angle of the blades has alot to do with how well a broadhead will penetrate on extreme quartering angles. In the article, the author shot a Rocky Mountain Ti 125, and a Ti 100. Made by the same company but the 125 penetrated much better on a hard angle shot. This was said to be because of the blade angle between the two heads not the 25 grain weight differential. Just a little insight.
