Well well, here I am in the SUP forum asking for board size advice! Don't tell anyone!

As an experienced shortboarder and kiter, I would like one for small swell and light wind days. Go for a paddle, take the dog for a swim, some fitness, etc. The missus will have a go now and then also.
My profile:
- 69kg
- 5'8
- Missus is 10kg lighter.
There is a second hand McTavish for sale. 9'6. Would this suit? Too small for a first time cruiser?
http://www.mctavish.com.au/surfboard/96-performance-supOR should I just get a second hand NSP (or they are cheap new anyway).
There is a bit of volume difference between the two boards. 150L to 205L.
I am not limited by the two mentioned boards - just what I have seen around. There is also a Hokua which appears similar in size to the McTav. Both are listed as "performance boards". Do I need an "allrounder" instead?Cheers!
