Hi Charlie,
I've had a couple of successful days with this fly,
Stan did an article on crippled midges in T&S that shows technique, I'll send it to you when I'm back from Ireland.
Essentially you tie a shipmans but stop at the thorax and leave the forward facing Antron long, so that you can lift it up as a post and add a hackle, you then finish dubbing thorax and pull the Antron forward, tie down and whip finish. You then trim as per Shipman's.
I caught on Big Red's bought from Iain Barr, they are one of the few flies in my box that I bought and have confidence.
