All very interesting chaps, thanks for your views. I'm fully waterproofed

so a bit of rain isn't going to keep me indoors supping a brew. In my very limited experience so far, the biggest enemy seems to be the wind, whether it's riffling the surface making flies hard to spot or holding back/drifting my casts. I'm due out this Friday, come rain, hail or shine - probably going to try Harelaw fishery near Neilston, south side of Glasgow, which is just a short hop from my house, and I can't wait! Has anyone on the forum fished Harelaw and, if so, what tactics/flies might work there?
