I have only ridden the big fish two times, so not much experience with this one.
But the 165 I know....
For my 72kg only, a bit too big/floaty, when really powered - but in "light" conditions things are different even for my light weight !
I've tested numereous different waveboards - but the JN Fish 165 has a really good glide, and the advantage seems to be, that it can pop out on the shoulder easily - so you can get really good aerial off the lips
When really powered, it is a bit too big for my lightweight - but otherwise, a great awesome waveboard IMO
