I was up there with a bud from Greenville on 9/16 and we floated. It was overcast and we saw a few blue wings early afternoon, then the sun came out and the Sulphurs started.
I was fishing a size 16 CDC comparadun sulphur with a 20 BWO sparkle dun dropper about 2 feet below. Started off catching fish on the BWO then when they keyed in on the Sulphur and I stuck to that.
Also fish a PT under and indicator in a size 18 and caught some nice bows.
Whenever they sluice the fishing is usually pretty good in my experience.
