Depends on what floats your boat...
For mine, its c) with a little bit of b)

I have the 11.5 (170 litre) and the 10.5 (145 litre) and REALLY enjoy sailing them.
They are very versatile - light wind wave sailing, fun freeride board (surprising to gybe) and schlogg alright in lighter breeze. (+ SUP if you are on the light side).
I seem to top the 11.5 out at around 28.5 knots in chop so bit of skill will see 30kts+. (although it takes a bit to wind it up - Cadillac not a Ferrari)
Not a speed machine, nor rad wave shredder, just plenty of FUN.
They are also solid so no need to replace every year, I would only sell mine to update to the newer model.
I note John Ingebritson just won the Florida (=crappy side-on mush) wave comp on an 11.5...
