Nice testing day!
Quite light wind from the beginning. I switched between the Isonic 117 and Isonic 107 (with 7.8). The Isonic 117 is a really nice board with the 7.8 sail. For me, the Isonic 117 is even than the Isonc 107 with 7.8.
When the wind increased I took the 7.0 and the Isonic 107. This is a supercombo!! Good speed, perfect control, the gybing is fantastic...
Unfortunately some weed, so I was using the weed fins all the time. What worked best was Hurricane weed 36 with 117 and Hurricane weed 32 with 107.
