Schulz16,I've used an HHA Opitmizer Lite,Copper-John,and the Trophy-Ridge.I was pleased with the HHA and the C-J,but the T-R was'nt for me.Right now I'm looking into the Spott-Hogg Hogg-It,Copper-John Dead Nut Pro III,HTM,and CBE. As with all archery equipment,go to a pro shop you trust and try them out...Bob
