RE: Kombat 97, max sail
Just some observations re. Kombat fins.
'06 models were supplied with small wave fin and larger freeride one. This suited K's convertible use very well, but I've found that I use my K86 mostly with Select freestylewave 27 cm fin. Drake is too flexy unless you actually ride waves (but good in some b/j situations) and freeride is for the lightest winds only.
So, while '07 models come with only one fin (and this is a loss in a way), I think it's the right one with regard to board's sweet spot & range (confirmed this after a session on '07 Kombat).
