reflex slalom 9.6 or formula 9.7?

[sergiobrun]

What differences are there between these two sails?
Will the Formula 9,7 be best option for light wind slalom on a iSonic 137? (1,80m, 90kg).
If yes, will it need a bigger fin than the 9,6?
Thanks,

Sergio

Hi Sergio,

Yes 9.7 is better and same fin will be ok. More stable and lighter.

All the best
