Not sure if you build your own rods but there are some good deals floating around the internet on the rainshadow RX-7 switches in the 5-8 wt range. I ordered up a 7wt last week and currently waiting for it to show up. I have heard some great reviews on that series of switches. Beyond that I don't know much as this will be my first foray into switch rods. If you give All About the Fly (site sponser) a call they should be able to get you dialed in for lines and rod recommendations..and I am sure some of the more knowledgeable folk here on the board will pop in shortly.
