Ianinca I had that board,and it was very slow to paddle,keeping in mind that it's the design elements in the board,super soft rails in the tail and heaps of tail rocker.... totall noserider design! All about suction and drag!!! But in the right conditions they noseride unreal! I moved mine on pretty quick,as I prefer some edge in the tail and flatter rocker of the striker ,which paddle heaps faster and noseride almost as good.At 75 kgs you are right there will be plenty of float and you may not feel as much drag / resistance,as I was 90kgs at the time.But if it's about hanging toes it's a very good design

I've got the 9'6x28" B&B and about your weight, paddles pretty fast for what it is, I pick up a shed load of waves, reckon it would be good for what you want.

Yeah, I have the 10'6" and I've used it for flatwater, definitely not a speed demon, not what it's made for. It is however, absolutely my favorite board to ride, great noserider. So if you ever get into surfing small waves, it's a perfect old school, longboard noserider.
