Good review Matt.
Yes, about the IS101 (mine is also from 2009) I have the same feeling. Damn good.
The best board I've ever been on. And I compare with other boards like the Falcon and the JP slalom.
I always feel the fastest on the water with it. I have the same feeling about my IS87.
I can't say the same about my IS122 (2008). It feels stickier on the water. Perhaps I'm not using the correct fins with it.
I use a choco 43 with the 7.8 and a 46 with my 8.8 sail. Anyway, much better than the red drake fins that came along with it.
When I put my mast foot far to the back to get more lift, it helps.
My expectations of the IS110 as a replacement are therefore very high.
I have the impression that you use the IS110 with rather small fins, which could indeed explain the issues with pointing.
It's a pity that you can't compare the IS110 with the older IS122.
Matt, may I ask how much you wheigh ?
