Hi Liam,
The arms were suffering after Wednesday's action! Yesterday though, the trout I caught were all on a pretty slow sink and draw retrieve with the odd tweek here and there to attract their attention. Many of the fish took the fly on the sink and even as soon as the fly hit the water. Great fun when two go for both flies at the same time!
The corixa was good for fishing the margins and the black fritz got takes from any fish that showed itself on the surface when you covered it.
