I wholeheartedly endorse the ocean/dynamic location with a WW boat. In fact, I'm a bit of a pain in the A$@ about it to some of my paddling buddies (such as NickJC). Those short little WW boats will allow you to get in close to features, in conditions, that you would never approach in a composite sea kayak. They'll also wear you out trying to get anywhere.
And for those of you who don't see the similarity of WW boats to sea boats give it a shot. You may be surprised what that 8' long boat can do in the right location that your long boat won't.
