I used the tekans last season and they fly and penetrate great. The only down side I see with them is the only have 2 blades. I tried Slick Tricks this season and like them better. They fly just like field points out to 60 yards, and probably farther. They have 4 fixed blades with 1 1/8" cutting diameter and penetrate like nothing I have used before. I killed a 380-400lb bear a month ago with them. Quartering away shot that broke rib on entry blew thru both lungs and broke its front leg. The brodhead looks and feels like it was never shot. Cuts paper!! First time I ever put a brodhead back in my quiver. The Tekans bent after impact of bone.
