A:
Salt water poles are night and day from fresh water poles. I've found that the MH saltwater pole is much more stiff than I would expect from a MH freshwater pole. The handles are a different size, and the reel sits differently on the pole for a saltwater rod vice a fresh water rod.
Still, it's like comparing apples and oranges. I recommend getting the best rod you can get to handle the size lures you're going to be throwing. Medium or Medium Heavy is a good choice for starting out. I've really enjoyed mine for striped bass and bluefish.
