I'm a newbie to SUP and I've decided to buy an inflatable SUP around 10-11 feet long.

I'd like a board that goes in a straight line (not necessarily very quickly), is good for catching small (Darwin) waves, and that is stable. (I am 76 kg, 6'3" no surfing background.)

I'm thinking safe choices are:
Red Air 10'6"
Naish Mana Air 10'

but am wondering if the less stable Naish Nalu Air 10'2 might be better for me after a few runs getting used to it.

Can anyone advise?

Thanks!
