Not to start another broadhead thread but lets say I have slick tricks flying good but have 80 lb ke would you shoot a fixed head or go to a mech head to get the bigger cut? Please tell me why and which head you would use
I have a pile of Slick Tricks, and I also shoot a couple flavors of mechanicals. Slicks and similar heads are suitabe for any game, with any responsible shot. Mechanicals are fine as long as you respect their limitations. Some mechanicals are better than others. It's important to understand that the size of the cut will never compensate for a lousy shot. Some 2" cut designs are an engineering disaster, and will literally fall apart on a solid rib shot.
It's up to you. I have a supply of Rocket's and Spitfires, and shooting several deer a year with both, for I'm not sure how many seasons, I've yet to have either design fail mechanically. I've bent a couple blades on shoulder shots and leg bones on the exit side, but I've never damaged the heads. I have a leg bone from a nice buck in my basement, with a 85gr slick, buried past the blades, still intact by the looks.
I will continue to use both types again this year. From my "doe bows", a 51lb Turbotec, and a 52lb Vulcan, I'm set up for 85gr Slicks and 100gr Nitrons. In my experience both designs will consistanly pass through a whitetal doe even with lighter arrow weights. From my heavier rigs, I'll use the larger cut (1 1/4"-1 1/2" cut) mechanicals because I know they will work on any deer, any responsible shot, as far as I will take a shot. With 80lbs of KE, a BH that will hold up is more of an issue than anything else. If you go with a mech, use a good one with a sturdy ferrule, plenty of blade thickness, and a simple design.
