Tied on the hook of your choice for the size prey that you are after.

For longevity I always double half-hitch after tying on a material, and usually add a drop of my head cement. (I use latex clear varnish, because a pint is real cheap and it is the same as most all water soluble head cements!)

About six strands of flashaboo, (or krystal flash) your color choice tied on first.
Then about eight strands of the smallest rubber you can find tied on top.
Then lay a piece of yarn, (I use orange plastic canvas yarn) on top the hook so there is about an inch hanging over the hook bend, and the eye.
Tie this on and then pull the end that is hanging over the eye back so you can tie it on top to hang past the hook bend.
Trim all to length of your choice.
The smaller the rubber, the more movement is visible when you hook a red worm once in the middle! It works on a flyrod without bait also.
About three foot of leader behind a torpedo, and work out to deep from weed edge works great!
A tip for those torpedo bubbles.... tie them to the leader so the small end is toward the fly! (Less resistance means more bites that hang on longer to let you set the hook!) Also, always tie a swivel to the big end of the bubble so you won't be twisting up your line on every retrieve!

Happy catching!
