Thanks for all the answers.
I decided to go for the 107, much because I found a used 2012 board, much cheaper than buying a new one.
Now I have to decide if I go for the 117 or for the 127 as the light wind board. if I go for the 117, I will have 8.6 R2 as the larger sail. If I go for the 127, will also go for the 9.6 R2.
With a weight of 84 kgs, what would be the best combination, 127 / 107 or 117 / 107? Any opinions?
For a smaller board, I have an older Falcon I will keep for now.
