Thanks, the board will besides our own use at times be used by friends which partly are novices in the surfing business. If they are really a starter I will rent a board at the local shop at the beach.
Acording to me the Go 129 is very simular to the carve 133 which means both stability, comfort, perfomance and fun. A true allrounder as it seems to be. However the Starsurfer M also seems to fill these demands
Hope this gives new insights in my question!
