when choosing broadheads keep in mind that a with a fixed blade broadhead, your bow/crossbow must be tuned to the fixed blade. They DO NOT fly like field points! Mechanical blades fly identical to a field point of equal weight. No special tuning required with mechanicals, sight in with your field points of equal weight, and your all set to use the same weight mechanical. With mechanicals I shoot 1" groups at 30 yards....and 3"-4" groups with fixed blades. Although fixed blades are damn near indestructable.....I'm hooked on mechanicals. Im not giving any advice, just my opinion and experience with shooting both type of broadheads.
