I had a morrison with Carbon/FC limbs, no tink. I now have a Sas with 2xCarbon, no tink.
I did shoot with a friend a couple years ago and there was an audible TINK every shot. He thought it was his bow quiver and in the quiet of my back yard, the TINK was quite loud!!
So we took off Quiver. TINK! wasn't that! then I stood close as he put an arrow on the string and shot...TINK!
Turned out his arrow nock fit on the string was a SNAP fit...when it released, there was an audible TINK!
point the arrow at the ground, tap the string and it would NOT come off... we sanded ONE nock slightly till it released with a TAP on the string but stayed put from the EFOC arrow pointed down.
NO MORE TINK! Fwiw!
