I've owned the Sage 590 RPL and replaced it with the GLoomis GLX so I agree with those two choices.

I would add the Fenwick HMG that started the graphite rod revolution. In my view, the difference between the HMG and fiberglass fly rods was huge, greater than the dfference between the rods in the article and the fly rods they competed with. The only rod that came close to as much a perforance leap was the GLX compared to the fly rods of its time.

I still use my GLX for Montana Fishing.
