Hi mate, seeing as I own a Hipster Twin you can guess my vote

My 8'6 has plenty of guide, no the fastest but catches any bump or wave I paddle for. Stable waiting around out the back and fun as advertised on a wave. The board turns when you get your foot back over the fins, and is flat enough under your front foot to get over dead sections on waves.
The 8'3" size might work well for you.
I have the shallow tail model, the new pin tail as shown on the WSS board's website look fantastic.
If the twin set up is something you really don't want, the Starboard Spice might fit the bill as you can run it as a quad or thruster.
You can find a review of the Hipster I posted a little further down this page.
Cheers.
Steve.
