where there's smoke...
Ahhh, Flytyer, there was no smoke as there was no Flytyer and hence, no contest.
I deduce from your message that you have had good success with the fly, which is good. It is a more simple tie than the LaFontaine pattern but does share a similar profile. LaFontaine's pattern and the Mathews' X-Caddis were the two that the Miracle Caddis was drawn from with more influence coming from the X-Caddis.
