I think they may be referring to unhooking in down the line wave riding. Regardless of that however, I find you can still unhook with the Pivots when riding freestyle. Due to the drifting characteristics though, the slack line is almost non existent making passes more difficult. You need to load and pop with a fair amount of effort compared to a C oriented kite. I ride 95% in the waves now but the 5% free riding I get to do is awesome
