Well, okay, again, that's up for debate. And, of course, a story goes along with the pattern. For many years, this WB was my pattern of choice when it came to stillwater with a Woolly Bugger. Everyone in our group used them so if someone was catching fish and indicated what they were using, they'd call it a variegated black and olive Woolly Bugger. For years, I thought everyone was tying it the same. During one trip to an Oregon coastal lake, I forgot to bring the box that included the pattern. John was catching trout with a variegated black and olive so I asked if he could loan me a few. He did. What he gave me was WBs with grizzly instead of black saddle hackle. I told him that wasn't the pattern and he said that's how he always tied them. So for years and years and years, John and I were catching trout believing we were using the same pattern and weren't! Sheeesh. Just to be on the safe side, I now also tied the pattern with a grizz hackle and carry both styles. The only time the pattern worked great for me in a river was during one trip to Yellowstone. On a whim, I tried using it with a sink-tip on The Fire Hole. The browns loved it. With that in mind, I thought I give the pattern a try at The Barn Holes. I was fishing it downstream, streamer style when SNAP! Something broke off the pattern. Weird. I tied on another, made a cast and again SNAP! What the heck was going on? I was using my normal 5lb tippet and usually that would handle the trout in the YNP area. This was a Sept trip and later that evening I was talking to one of the guys at a shop in West Yellowstone and they told me the giant fish from Hebgen had already started moving up the Madison in the park. (I wondered why anglers were fishing the Barn Holes with spey rods) I told him my story and showed him the pattern. A year later, I couldn't help but notice that the shop was selling the variegated black and olive Woolly Buggers... hmmmmm. Over the last few years, the trout in the coastal lakes don't seem to like it as well as they once did. I have no idea why. Maybe this year they'll decide to try and eat it again. I know I'll continue to use the pattern until I'm positive it no longer works.
