I've had some time to test out Star-boards Quads, 76,81 and I'm really stoked on them. They are some what of a cross between a single fin, twin fin, and the evo line. I've had them in a range of conditions from head high onshore slop, to over mast choppy side-shore and down the line perfection. The 76 is my favorite, I've never had a board work so well in onshore conditions and also have the ability to go top to bottom vertically. The boards have a whole different "pop" coming of the lip or hitting white water. They allow you to clear sections and make things you normally wouldn't. They're great boards for all conditions.
