I had some wasp hammer sst's that I couldn't get to shoot worth a dime. So I ordered some sonic 100 grain broadheads because they are supposed to "fly like fieldpoints." In the mean time I went to the Pro shop and let them make some adjustments and line me out a little bit. Well the sonics shot great just like my fp. However, when I tried my wasps again they did too. Long story short. After getting my bow in tune both heads flew great. But if you want to take the easy way out, the sonics flew true even with my untuned bow.
