backside: tri; frontside: single or twin

anyone agree with hynd on this point?

i just finished reading that, and some of what he said makes sense to me, but i dont know if it is so black and white. it might work for him some days on some waves and it might not others. but what works for him might not work for you. his ideas of how a wave should be ridden are refreshing when looking at modern pro surfing. as for what kind of board to ride “backside: tri; frontside: single or twin” is an over simplification.
