Bucknastys on very impressed
 

Just installing two sets of John's cables and strings on a Matt-Q2,BT-MM. Put about 15 shots on each installed peeps,after 100 shots only the Q2 needed a little tweak on peep,best I've seen so far.I think I may have gained a little speed on both,had to reset gap on 30-40 yd pins after gang setting 20 yd pin. Thanks John!
