Do we fishermen/fly tiers rely too much on horizontal views of our flies?

[Byron haugh]

My original post used the specific example of the X-Caddis fly pattern. Hans mentioned his success with the CDC&Elk in mayfly situations.
I would argue that the CDC&Elk is substantively different in that the "flowing" CDC fibers present a substantially different look than a dubbed X-Caddis.

I will probably be faulted for my version of Hans' pattern, but offer a view of it as a trout might see it (second photo). Granted, it is dry and not on the water, but I think this is representative.

First the fly as we might see it.








Then the fly as the trout might see it. I think it is dramatically different from an X-Caddis from below/looking up..............
