The T-Heads are one of the sharpest heads out there, and a proven performer over the years. However you need to ensure that your broadheads spin true on your shafts. I have found that from time to time the little o-ring may not compress equally on all sides and cause the broadhead to wobble. You just have to be diligent about ensuring each broadhead is matched to an arrow that will spin true as a combo. Once that is done, you should be in good shape.
