Super - I decided on them because of the reputation of the other Slick Trick designs and because they have a cut on contact style and steeper cutting angle more in line with the Magnus Stinger, Muzzy Phantom and the old Bear Razorhead. All of which are basically the same profile. Another reason is my daughter-in-law and my grandson can only handle about 45# draw and the Vipertrick should be a good design. I personally have not taken any deer with them but I plan on it in a few months....
