We still have a Vivace 270 (my son sails it). I tried a 6.9 race (NP MKIII
WC) on it a couple times when the 270 a Vivace 290 and the sails were mine,
and it felt odd. The 6.0 (same type) on the other hand is pretty good, the
5.2 seems a perfect match and the 4.5 too small.
The newer larger race sails are flatter and feel lighter so maybe you could
go to 7 meters.
But the 270 is a pretty small (narrow) board to try to get going in 8-12.
