I shoot a 2000 Maverick Express with Recurve limbs. Starting last year I started struggling with consistancy so I switched to a back tension release. I felt I was shooting it properly and shot better, but not as well as I used to shoot. I paper tuned the bow and tuned it to shoot bullet holes. Still having consistancy problems. I noticed the tuning mark on the control wheel was right in the grooves, but the cable was well out of the tuning marks on the cam. Well, I just got a new string and cables put on the bow and both are within the marks now. I am now shooting the way I know I am capable, as just yesterday, I shot my best 3-D round ever shooting a 356 on a 36 target range with standard 12/10/8/5 scoring. I am so excited I can hardly take it today. I am very pleased. Sorry for the life story, but I was wondering if any of the other Darton shooters have had this type of problem with the CPS system? If not, any other suggestions as to what the problem may have been would be appreciated.
