I STARTED WITH A LONG BOW 72 YEARS A GO I have used and made fly right many different kinds of broad head, the different types al have certain advantages. Different ones fit different peoples needs, for instance kid and small woman should use fixed broad heads they don't have enough momentum to properly operate mechanical's; on the other hand people who use heavy draw bows and hunt on the open plains and have to deal with wind and shoot long range or people who hunt in heavy brush like me are much better of with mechanical's if they use good ones there is a lot of junk on the market . I have use Spitfires with 100 percent pass through for more than 100 and 20 deer since I started using them I shoot a heavy draw that gives me 140KE and most of my arrows are stuck 3 or 4 inches in the dirt after passing through the deer. If I can handle a decent draw weight at 82 year old then most should be able to I understand the kids and woman need a light bow my wife only used 52 pounds draw and used Satellite broad heads.
