Buy dedicated foil board , you will never normal sup surf again. I know as I went thru the same and it just put me back 6 months f#
@king around with bad equipment. Your light and so many more foil boards suited to you and with start of spring lots of boards will come up on seabreeze as we go down in size, I am about to list Naish 135lt 7'6 foilboard which finally got me going after using cross over boards that are designed for surfing not foiling, you may as well just convert an existing SUP as its the same thing. JMHO its addictive.
