This could be a sound off topic but it should work here too.

I have watched a lot of experts tie at expos ,etc.....and have wondered...as they tie with one wrap here and two wraps there...or this material here and there...are they really tying flies that will hold up to the rigors of actual fishing?....or are they tying what looks good for demo purposes???

I know some of our gurus are practical but do you think this happens?
