The problem lied in how they were attached. You were supposed to bend the tip of the bleeder and insert and the bend would keep it in place. Well, it worked, but I never liked it because the bleeders would never line up straight. My brother shot the 160 grain for years with bleeders and he would super glue the bleeders in place, without bending them. He had great luck and killed a pile of deer with them. I never really fooled with the bleeders, but have had good enough results that they are the only broadhead that I've used for the last 20 years. They now have locking bleeders for the 100 and 125 grain landsharks. I shoot the 160 grain landsharks, the Interceptor and a Treeshark from time to time. DON'T JUST BE TEMPTED TO TRY THEM, GET YOU SOME OF THEM!
