That old worm of yours is a Riverside Big Wag.  Disocntinued long ago.

Lurenet is Pradco's ecommerce website for all of their brands under one roof.

A very close model of worm would be Roboworm's RoboTail, but it is only in 7 1/2" I believe.

yeah i did some research a couple months ago when i was still fishing before winter and i did find out that it was the riverside big wag. i cant find a good substitute, that producto lure is probably going to be the best sub. (7.5" robo worm is too small)

A good alternative would be a 10" culprit worm.

Yeah, it looks a lot like a culprit to me.

I find it funny no one has mentioned the Zoom Ol' Monster or Zoom Big Dead Ringer. Both are phenominal worms IMHO. We use them on the big G in the summer swimming them along the grass lines and fish absolutely hammer them. Just another alternative.
