Paul, How are you using the split-limb adaptors? They work pretty well if put on the bow right. I hook mine on the limb with the adaptor between the string and the cable. This way they don't interfere with the string when the limbs are depressed.

Junst thought I'd mention this. I did it wrong for a while when I first got them. I even got to where I use them on solid limb bows like my Martins.
