Just wanted to share with you guys after getting plenty of feedback.
Here it is!
LE 12'6 x 28.
Just had it out and there were about 16 knots cross in the fjord, so kind of tough, but downwind it glided nicely in the chop, and in flat water in the harbour, it was really fast.
I didn't use a pulse belt or GPS watch, but felt like I got my heart rate up higher than on the Nalu, probably because the speed and acceleration is kind of motivating.
The board also felt pretty much as stable as the 10'6 x 30 Nalu. I don't fall off that when paddling in reasonable conditions, and didn't fall from the Javelin either.
My first impression is very positive. It is definitely plenty faster than the Nalu. I am going to use GPS tracking next time around to get an exact idea of the difference.
