I took a couple Double Pink Weenies out to do a little field testing the other day. It was one of the least promising days for brim that you could have imagined. Bright, still and very hot. Still and all, I caught four nice brim in the first four casts. The brim held on to the flies for a much longer period of time than was typical. I purposely avoided setting the hook on one fish and it actually swam around with the fly in his mouth for several seconds. I believe Koosh Ball spikes have a life-like feel that is missing in most fly tying material. On these flies, I used a #10 nymph hook which was 1X longs and 1X heavy. The body is pink ice dubbing and the appendages are four weenie ball spikes. The fly settles slowly in the water column and most fish took the fly when it was just sinking without additional motion. The exception to this occurred when a good sized catfish grabbed my last weenie in shallow water and broke the leader. I think there is real promise in this material.
