That board is just too long and too narrow for freestyle. You have to look at a shorter and wider board.

what is the downside of the dimensions? Is it too unbalanced sideways due to narrowness for landings? Swingweight wise I would not think to be a such a big factor if the board is very light?

There are some strange responses. Of course you can pop frontside 360s on a 5'8". Sure, it's not ideal, but totally doable. I used to ride a 5'4" x 26" board and it rotates through a 360 without any issues. An extra 4" of nose won't matter.
I haven't tried backflips, but I when I do, I'm going for a short nose board to make the rotation easier. I'm sure someone who can do backflips, can do it on a 5'8" board too.

4.2kg sounds too light to be a robust board. Freestyle boards are usually heavier than that because they are built with extra reinforcement.

I have two boards that are about same weight. Other is long and narrow 6'0, 19'' 92l, other is compact 4,7 72l. With shorter board jumping 360, practicing flips no problem. Longer board is just horrible to jump even straight airs. There is way too much swing weight. Also on takeoff, nose of the board can clip the water much easier. Before landing, controlling fore-aft balance is harder. I would not even consider doing 360 with that board, let alone flips Yes, theoretically everything is possible if you are a pro. But is it easy or enjoyable?

He's talking about a 19,5" narrow board. Believe me, that is too narrow for freestyle.
