My main stay fly rod(s) are 5 wt, so much so that I have three of them: two niners, one a fast action and the other a medium, plus an eight footer for more close quarters. These 5wts probably account for 90% of the fly fishing I do.

However, an old favorite (well, about 18 years old?), that seldom gets used ... is an 8'6", 7wt IM-6 graphite Pflueger, bought at (of all places) K-Mart. Beautiful action rod that will handle it's own performance wise against much higher priced/prestige rods. I'd use it more except as already posted, 5wt is more my everyday style. But when I do use this rod it is always a pleasant surprise - so much so that I matched it up with an old (made in the USA) #1494 Pflueger reel - great combination!
