    Bombshell works at treat in my 9ft SUP

    Just had a couple of surfs in some West Oz waves using the new GOHARD 7" Bombshell on my 9ft SUP. Works a treat using with Fastlight 7s in thruster setup. Loose and fast but hangs in on the critical sections. Can't wait for the Hangten side fins to come out in futures setup, reakon that will rip too.
