Plunking is a very effective way to catch fish, especially in muddy, high water. I first learned how to fish by plunking on the Puyallup back in 1975 as a youngin (quite literally, I was only 5). I've found it's best to use a standard "plunking rod" all year around. In the circle I was in, most guys used Older Fenwick 88c or 89c with either 7000 or 6000 Ambassadeurs on them. (I have a couple, but mostly use my 88c with 6001c). Since you want advice on summer runs, I'll give you this scoop. Go smaller and lighter. You can use whatever you use for mainline, then run a swivel followed by two beads then loop a barrel swivel on end of mainline. From your snapswivel put either a 4 or 5 ounce pyramid sinker on about a 6 inch dropper. With summer conditions I run Ultragreen in around 8lb test with about size 2 down to 8 hooks with either strait eggs/sandshrimp with maybe a very small clown spinglow. Add the shrimpoil, it helps alot. Set the rod in the rodholder and hang on. I have been very successful with plunking, but I only do it when I need a break from drifting/fly fishing. If we hook up for those Kunnan's, I can show you some plunking set ups. I have two rods set up for different conditions. Everyone has their own ways, but this is about standard practice from oldtimers on the Puyallup (only problem is most of the oldtimers I learned from are dying off except my Dad). Any other help, let me know.
