For a while I lived on a lake west of town that had a few square acres of mud flats that lended itself to some supreme carp fishing from a kayak. While there I honed my technique and worked on fly patterns to target these fish that can vary from lazy to super skittish and nearly impossible to approach. Once I moved I found that most of what I learned there translated very well to the slow pools and eddys on rivers around Columbus where the carp tend to hang. Working with some materials that were relatively new to the market back in the spring I tied up some new prototype flies and threw them in the boxes. After a few times out, and a few tweaks, they were performing exactly as designed and were put to good use as a 'craw-ish' imitation fooling fish. Neither fly is what I would call a realistic imitation, but rather is more of an impressionistic fly that simply looks like food.
Mike's Gorgon Craw makes good use of Senyo Shaggy Dub and barred rubber legs as antennae and claws. The grizzly marabou both provides a mottled look and 'movement without movement', in other words even in between strips the fly appears to have a little shimmy. The bead chain eyes are enough weight to get the fly down where it needs to be, but not so heavy as to make a commotion when entering the water.
Even more impressionistic is Mike's Hairy Nibblet. It more or less looks like a soft craw in a defensive position...but not exactly... Again with the bead chain eyes for the same reason as above.
Both flies were designed to be effective but also quick ties since you will lose some as they generally need to be fished on the bottom. I keep them in my box in Tan, Olive, Black and Rust. As far as size I have found that 6, 8, and 10 pretty much cover it, and in my experience a size 8 carp fly is generally my go to size.
Happy carp hunting!
