Getting a fly to dance back and forth in a walk-the-dog action is not as easy as I thought. There are tons of posts on flies that do it, but none of those posts explain exactly why, or how to troubleshoot.
The head of course, is critical. The weight and materials used, just as much so. I personally wanted to get this set up working with a trailing hook, to fool our spotted friends on the Breede. I figure watching one of those surf in while trying to eat a big popper would be cool.
At about 10pm on Saturday night the ball dropped. And on attempt number 20 something finally worked. the umpteenth variation of materials and weight. Before I left I made another crucial discovery. Its not asymetrics of the head that cause it to favour a certain direction, its the resting stance in the water. It makes perfect sense now, if its lying on its right, it favours the right. But no one tells you this shit.
A cool little trick is to tweak the weight using UV resin while you’re on the water to make sure it sits even. And yes, I got it to work perfectly with a trailing hook….and two grunter tried to suck the bugger in.
