I love fishing WITH an indicator, but the indicators themselves almost always get on my nerves one way or the other. I do try to use the smallest indicator I can that will stay visible while what ever fly(s) and hanging below it. Lately, I'm pretty loyal to Floatmaster stuff.
I fish the White and Norfork rivers. I use the standard stuff that works here. Zebra midges, PT's, Prince, GRHE, Copper Johns, Scuds, sowbugs. Egg patterns October thru April or anytime the water has some stain to it.
