Looking for some help here. I'm an intermediate surfer in Bay Head NJ and currently have a Biscuit. I'm looking to get a board with a little more performance design to it, but not ready to go to a "real" short board. I'm 6', 160 lbs and mainly surf East Coast waves. My current considerations are a Dumpster Diver or a Motor Boat. Should I also consider a more traditional shape like the Fred Rubble or the Dagger? Yes, I am partial to CI boards and have been since I was a teen.
