Ask Canalman...
Some point this winter there will be a half-ass article by some hack writer from Gansett
I love rigged eels; Probably 30-40% of my summer fish are on riggies
Small eels: single 8/0 siwash
medium: two 7/0
Large: 9/0 head 8/0 back
I bury the head hook, but add a swivel to the front hook... thats whats exposed...
I agree with swimming them in the day-light, at least some to get a feel for it.
Best advise I have on them is to vary your retrieve all night until you find em!
Sometimes fast like McKenna sluggos
sometimes super slow like live eels
Usually somewhere in between!
