Sonics are very under rated. There only draw back is they can get ruined if u hit bone of rock, but we arent aiming for bone or rock. Im using the sonic pro 100 grains this year. They are the only broadhead ive ever shot that hit exactly with my field tips. Other than mechanicals of course. Im glad there is someone else on this forum who likes them. Also, very accurate at long distances. Alot farther than id shoot at a live animal. I killed a squirrel at 45 yards. Lucky? Yes. But they shoot as good as my FPs.
