Just bought some of the Frog Hair indicators, medium. I put one on my 6wt and I think as far as indicators go these might just be the best. They don’t pinch, twist, knot, or leave sticky residue on the leader and they stay put. It was very easy to adjust and seems like the ultimate indicator, so far. I still haven’t tried Zach’s balloon method. The half hitch knot scares me a little.
I have tried them all and keep going back to a little corky skewered with a tooth pick. I am drawn to fast riffle and pocket water and have found that a corky floats a couple of flies and BB’s the best. A nice additional advantage is that the tooth pick always points to where the shot are and offers a nice aid in visualizing what is going on with your flies.
I have tried the Frog Hair indicators and really liked the system. I think the ones I have might be the small size and are just not big enough for what I want them to do. Maybe some in a bigger size are in order for a field test…
