BP,
if you haven't got excellent balance, don't have some sort of water-sports experience under your belt, &/or are not a lightweight, then you're going to spend some time falling off initially no matter what sup you're on. The smaller (shorter/narrower) the sup, the more you're going to fall off.
It depends whether you don't mind working harder to surf the board, rather than working harder to paddle & balance. If it's the former, go longer.
There's a guy over here who's an experienced longboarder & experienced paddle-boarder. Not sure how much he weighs, possibly a bit heavier than you (95kgs??). He bought a new sup a few weeks back: 10'6" WAA, loves it.
