Rick,
Once one has the material, tying these flies is like tying woolly worms without the palmered hackle. They're so easy that I am not sure if there is enough there for fly of the week. As for samples, I am sure you could make better ones if you had the material. Check for a PM from me.
Bill,
Check for a PM from me.
Robin,
The 5" worm has bee the best so far.
