Nothing wrong with Mechanical's ,there's some real good one's on the market today and they've really come a long way . But yes you need to tune for some fixxed head's ,but if you want to find a fixxed head that will fly ewith your field point's Slick Trick's and Montec's are among the leader's . But at this late date ,I'd say stand pat with what's working for you now .
