500, you must be the KING tuner!!! Those are some great speeds from a 7 7/8 inch brace bow I don' t want to hear about you bullying up on some Black Max II though[] Mine is driving tacks and shoots a little faster than my ' 02 Pat and 6 pounds less draw, can' t wait for antelope season! You are right about these bows responding to a super tune! Have a great weekend[8D]
