I have a question... why would you ever use anything but a short FL fresnel to collect light from your lamp? It would collect a larger arc of light (be brighter) rather than a long FL, which only collects a shorter arc. Even if you have a loooong front FL for a long-throw lense, you'd still want a shorter fresnel to collect the largest light arc.

Is my logic off there?
