Yes Ric, there are times when rainbows can truly give you the heebie-jeebies. There they are rising and rolling all around you, and try as hard as you can you can't get a touch.
Yet the odd still water brownie will still have a go.
Basically rainbows are a lot less catholic in their diet than browns and have a greater tendency to preoccupation with one particular food form. Yet at times they will grab a dirty great black lure when they are preoccupied with daphnia for example.
And you have to consider the environment. A still water trout has all the time in the world to inspect your imitation. On rivers they will either grab a fly or they won't. Personally I have fished both still waters and rivers in my life and don't know which I prefer. One thing I have learned over the years is that people who say that still water rainbows are easy, just haven't spent much time fishing for them.
