Bought a Bowtech Destroyer 340. Had a Mathews FX for years and have always used NAP 100 gr. Thunderheads. The bow shop I bought the Bowtech from suggested that I use a Carbon Express F-15 Fixed Broadhead, I dont use mechanical, I just dont feel comfortable with them, not saying anything bad about them. Its a broadhead that came out somewhat recently, wondering if anyone has used them and do they hold up to the claim that they shot as good as a field tip. Also how good is the wound they leave?
