Don't split a Charlie Slasher to have as your main split. I have a CS and I fucking love it. It absolutely slays the shit out of some powder. However, in variable conditions, it pretty much sucks. It's a dedicated powder board. Not only that, but I don't trust it to hold up. Mine has done just fine, but I only take it out on deep days, so it doesn't take too many hits. Splits take a terrible beating. Split something that'll take it. I just can't imagine a board that light would hold up. The CS is shockingly light. My 164 CS is easily the lightest board I own and I own boards that are 8cms shorter.
