This is Mark, from Dharma of the Drift. Just had to send you an email about this..
A friend of mine, a hard core carp angler (in the euro bait fishing style) invited me to come carp fishing with him next week, in a place that he said I was likely to be able to take one on the fly. Having never hooked a carp before, I eagerly accepted.
In anticipation, I started tying some carp flies today, and remembered your backstabber pattern. So I pulled up your blog and got the step by step on the screen and tied up a half dozen or so. As I was tying I couldn't see any reason why they wouldnt work for other species too, so I decided to take them out and give them a try. A few hours later and I hooked and landed my first fish on a backstabber...and what a fish it was. A big beautiful tiger trout, easily my best trout of 2011, and maybe ever (gotta measure the rod in the picture as a reference and see if it's at least 20").
Anyway, I just wanted to let you know about another backstabber success story!
