Don't waste your money on something that you won't be able to tell the difference on. That said, if you got the money, the surf industry needs people like you, so spend spend spend ! But if you don't have extra funds ( like me ), visit your local surf shop that has the FCS "Test Drive". You can borrow a quad set for free ( you only get charged if you destroy them, lose them or don't return them ). Who knows, maybe a "Large" set isn't right for you. But once you buy them, there yours.
