Ahhh Ron, provocative as ever

As I am sure u are aware, the strike indicator/bob was *invented* for river nymphing when using heavily weighted flies in rough and turbulent runs. As the tip of the line is impossible to watch in these circumstances, a sight bob is indeed needed to spot takes. A secondary benefit is that the nymphs can be suspended above the stream bed at a pre detirmined depth.
If you have ever had the pleasure to watch Polish trout and Grayling anglers in action, you will have seen the great skill that this method commands.
HOWEVER, like all good things, people take the idea and adapt it for there own use. Now, in my own opinion, for what it is worth, using an egg fly and indicator, and sitting on the bank is not fly fishing, but it is a legitimate method!! (unless banned) Some anglers would class lure fishing as not being Fly fishing...others that only upstream dry fly fishing is the "true" goal.
I guess I use a strike indicator when using a team of buzzers, in the form of a large bushy Shipmans, a Daddy Long Legs or similar on the top dropper. I cast across the wind and let it drift. Am I in the wrong? This is a method mentiond by Bob Church, Steve Parton etc in the 60's and even the great Arthur (i think) Cove did this. Thats 40 years without a complaint.
I think the problem lies with the interpritation of a method, not its actual use. What do u think?
