I have never used the hammerheads but have considered trying them many times when my Steelhead XL supply began drying up, but found relief when Rocket brought back the Sidewinder, Hammerhead and Steelhead(Regular 1 1/8). I have probably 50 original Steelheads and 1 of them has now been through 9 deer and 2 turkeys. I do like the extra cut on the XL's in my faster bows and continue to use the smaller Steelheads for the slower bows to maximize pass through possibility..
