Troll got trolled

Love it.
Sounds like you have a few anger management problems you need to work through kotp.
Can a full surfing roundhouse cutback be achieved on either a windsurfer, or a SUP?
Do you kite?
Assuming a 'no' answer to each question (highly likely), let's break this down. You have come onto a forum for a sport you don't participate in, criticising that sport for being unable to complete a maneuver that sports you participate in are also incapable of. In effect, criticising yourself.
Further, in the process, it has been revealed that you SUP in fine, high performance reef waves, where an 18 1/2 inch pintail is the weapon of choice, on a pink board (well, ship really) no less, whilst wearing foolish headwear, and trying to imitate a member of the blackshorts.
Even more distressing, you think that is so cool you post pictures on the interwebs.
IMHO, it sux to be you my friend.
PWND.
