I've used Sonorans for several years. I like the design, and they fly very well. Killed one hog with them; it only went ten yards.

Be advised that the "100 grain" heads actually weigh 108 grains, which isn't a big difference from your 100 grain field points at any reasonable distance.

Also, make sure that you sufficiently heat up the shrink tube so it grips TIGHT. Or make sure you don't stab the heads too deep into the quiver foam. (I did that once. The loose shrink tube slipped off the head, stayed in the quiver, which caused the blades to deploy in flight.)
