Tyelino,
I agree with Billboard. However, this board seems to look OK. But you never get a genuine look until you see it in person....
However, you are a fair dinkum lightweight at 60kg, punching outside your weight division with a 75kg wife !!



Do your mates drink you under the table!? Sorry, I digress...

Go and see the guys in the shops... But if your budget is super tight, and you haven't surfed much in the past, you will probably enjoy that board as a good intro. Even at 10'6, it would appear too big for you, but if you are new to surfing and SUP, maybe 10'6 is a reasonable starting point for you both.
10'6 will be OK for her in the flats too.
But you should go through the effort of a few demo boards, and if you are new to it, demo in the flat water, not surf. Maybe try and do some training session at Currumbin too. (?)
