i've seen a guy flying the 12m sling a few weeks ago.
i was impressed
very stable and good looking.
he was still riding it with a 138cm wakestyle board when all others used 16m rhinos and 11.8 airblasts and i had no chance with a 12m rhino and a 6'3" board.
after all i've heard, the slings do not have
a big depower range using the chicken-loop, but you can reduce the power really good by edging the board.
so if i wanted a kite for ripping hard with a small board, the sling would be one of my favorite choices.....
