not too many thigs to add to your choose... the "brief" what you give is covered by the SUPer 10 the best. the 12 and the12'6 would better for flat water paddeling, but all the rest of the advantages on the 10.
the 6,5 SUPer sail would be a nice partner for the light wind freestyle - if you dont want to kill your monofilm sail. the "all in one bag" need very small place. (and its very affordable)
