I just had a Mathews Center String Stop put on my new to me Mathews Denalin and LOVE it!! I added a 1 inch longer draw length cam and it gained me 10yds with my pins. I then added the string stop and it as well added 10yds to the pins, not too mention quieted the bow to the point you almost barely hear it go off in the shooting lane, indoors!!!! Even took the nearly un-noticeable recoil away. worth what I paid for it. Also got new limb and string dampeners in orange color and alternated them with the black ones to give me a Harley Davidson black and orange theme.
