Example, would a 8' or maybe 9' 5/5 Rod work? Have enough length to properly cast a fly? Same goes for longest. Is 15' that magic longest rod one could make and use effectively unless you are like a 7' Shaq-attack or a 3' Mini Me for the shorty? - insert in your brain here a picture of MiniMe casting a Tenkara 15' rod.

Curious what you all think are the shortest and longest we may see in the near future.
