You have pretty much now answered the question !
A challenge ? Yes it will certainly be that.
Its too close in volume and sail range to be a "2nd" board.
The Hyper has a broader range of attributes.
You talk about 13 knots and 100 kgs, which brings me neatly to the final solution.
Buy it, love it and then flog the Carve (if you really only want ONE board).
I imagine the Carve will be easier to sell.
The ultimate solution though, is find an old Free Formula or possibly an early Formula and a 10.0 or 10.5 no cam sail.
You will double your (happy) planing days.
