WG,
The Clousers in the pic above were tied for the Sports Show CVTU booth and are thus very basic and meant to represent the standard pattern that folks would associate with the classic shape and materials of the "Clouser Minnow."
Personally, when I tie Clousers for myself they're considerably more elaborate and usually incorporate marabou or synthetics rather than the traditional deer hair.
Whether additional red would make the fly more effective, I don't know. There's a school of thought (or was a few years ago) among conventional gear bass guys that a splash of red in lures caught more fish. I think this concept was driven by the statements of one or more of the big Bassmaster Classic winners(?). In any event, the red fad went so far that treble hooks in red became a staple on many conventional plugs and lures. I'm a staunch advocate of following some of the cues/techniques used by spin guys in order to be a better bass fly fishermen. However, I'm not so sure the red hook fad is (or was) anything more than a fad.
But you know the old saying about fishing a lure that you have confidence in.
