Do you know ANYTHING about DOUBLE HELIX (PU) BOARDS?

Hey have any of you bros owned, or do you know anything about the Channel Island Double-Helix Flyer II and other PU (polyurethane) Boards? I guess CI is selling them at $399 and thats a chill deal, unfortunately I feel there is a catch and have heard only one time (which is enough) that they might be easier to break than a normal board. I can't afford for the new board that I'm looking to buy, break on me anytime soon. Please let me know if you have heard anything...
