Since you ride behind a Malibu 23LSV you should get the Lyman, since that is pretty much the same boat Keith has. He goes pretty big behind the 'Bu so you should be able to as well if you ride the same setup.
All kidding aside, the Lyman is an awesome board. It takes a lot of the good aspects out of the entire LF line and puts it all in one package. If you like a board thats hard-charging, consistent, has plenty of pop and lands fast and smooth, then the Lyman is for you. I am personally not a big fan of the PS3, but try them both.
