Aside from needing a bow press to move mine, does it make a difference if mine are installed thru the middle of the two shades of string? Do you have a third speed nock thats hidden from view? I have 3 on both ends of mine. The manual says they install 2 per side. Until I lost those high dollar stars, I had 2 above and 1 below each star. Also, if I back out the set screw, I' ll change my nock point.
