Wiggle Jig Worm
The rag worm imitation that will wiggle as you jig it
Maybe you found the tandem worm too tandemnised and would be better of with a one-hook-only fly.Then the fly The Wiggling Jigging Worm shown beneath is a good alternative.
It is strongly inspired by the fly Sandiglen (The Sand Leech) originally tied by René Hansen.
However, this version has added weight just behind the hook eye, so it will jig through the water and at same time make vibrations to the sides due to the Magic Head. It is a fly that is very much alive in the water and I am sure it will be taken for a small clam worm. It has the right movement, color and the characteristicly flat profile with all the legs.
Another great fly is the Omoe Brush tied by Ken Bonde Larsen on a trip to the small island Omoe.
