Mike,
My club had their 1st outing (Midmar) on Saturday - a day for staying indoors if I've ever seen one but I ventured out at 11am.
It felt like a typical Winters day so I fished my standard 'cold weather' set up. Floater, 12' leader (I was sometimes casting against the blow) , apps bloodworm on the point and a black and green buzzer on the dropper.
I had 7 fish spread evenly over both flies & interestingly enough I could only connect with fish when it was snowing, hail, or gusting - when there were sunny spells I could only get nips and plucks.
So I'll stick with the Apps Bloodworm as a favourite when it's snowing.
