ok, i see, on the siwash the shank and eyelet are straight up and the octapus has the slight bent back away from the point.
with a 4 mor 5 bead swivel on a plug and with water current plugging the plug down, wouldn't you want the hook to open up behind the plug. with the ones i set up all the hooks run point up when in the water, and with the octapus hooks slight open away from the plug. does not this leave a better bite area?
yeah, i hooked the swivel on the front eyelet of my plugs, big and small, all seem to run much truer this then with 2 hoks.
