Hi Chris, Ive just bought the sk3 which is 12-20lb test. I haven't used it yet, but it feels the perfect rod for inshore fishing, but I will also use it on wrecks too, as I feel it will be good for shad fishing with braid for most of the fish I seem to catch. What test is the sk4, I looked at them in ID tackle, but chose the sk3 just on a personal choice.
