I also just switched to the Wise Guy. Has improved my accuracy immensely. I will say if you go to try it get the nylon rather than the solid.Silverhorn was too touchy for me but has the same Scott quality as the others. Rhino is much better for back tension as has adjustability. I am shooting the Spott Hogg Wise Guy and its my favorite but have shot all three

The nylon gives you more adjustability with the length. With the nylon it allows you to be able to shorten the release enough to use your first joint on your finger if you so desired.
