Cool...glad you made that progression. Did you notice that, as you are able to fish with lighter flies, strike detection is amplified? I still train using heavy flies just to stay sharp, but when I have my druthers I find ways to make small flies produce--even in very heavy water. It is a confidence issue though--you have to do it and learn in order to see the results.. As the summer progresses, the heavy fly is going to fall out of practical use in most places.
I am glad it is coming to light that there are just so many details and applications involved with fishing weighted flies--it goes far beyond just czech nymphing.
Hoover...that fly sucks.
