I would never recommend that you remove the hooks, slide an eelskin over it, and use rodwrapping thread to tie it down in the recessed eye sockets. Never tie a double length of heavy mono to the back hookholder before you slide the skin on. The mono will never prevent the eelskin tail from fouling the belly treble too much. Never replace only the belly hook (no tail hook) with a larger size treble. It just won't work - and if you somehow get it to work, never tell anybody. It is our little secret, okay?
