I have an array of rods that vary in action, and they all see use for the intended purpose that I bought them for, including multiples of the same rod weights, but just in different actions. Yeah, for certain beaches when I fish for salmon or warm water where wind is usually a factor, I use a fast rod to help build line speed as well as help punch the wind without the line collapsing. At another beach and on a certain river that I love, when fishing for the same salmon, I use a medium to medium fast to help protect the tippet and also because it's more fun to play the fish on it and wind is not a factor. Same goes for my trout rods- two 5wts, one slow to medium that I use for lobbing nymphs and indi's, as well as for light dries, and another medium-fast that I use for chucking streamers and punching wind. I don't think that the whole 'Faster is better' mentality as an all-round direction for rod technology is a good thing, but I find certain rods and their actions have their place to help ME fish more effectively. I also find that certain rods pair better with certain lines, and that one line I use on one of my 5 or 8wt's doesn't necessarily cast as well on the other of the same weight. Though I do own a fair quiver of rods, I don't own any glass and am plan on getting a 3 or 4wt Butter Stick or something.
