correct, the board has a slightly stretched outline, but the overall bottom shape/rocker is now very similar to the 115, when you ride both they feel very similar, just the 107 is smaller. Before the 115 and 106 had a quite different feel and that's why we improved/adapted the 107 concept to be closer to the 115, which is one of our best allrounders. The 107 is for lighter riders and the sail range is obviously a bit smaller at the top end - so best sails are 7.0, 7.7 is ok, 8.4 is too big. 6.3 feels quite good on that too. For the 115, the best size is 7.7, 7.0 is ok, 8.4 is the limit.
