I have a Kombat86 (I'm also 85+ kg) and have chosen an Acid74 as a next smaller board. I haven't tried it yet, nor have I sailed Kombat79, so maybe I'm totally wrong. It seems to me that K89/K79 will overlap way too much (they will differ what - 2cm in width and 0.7m in sail carrying range?)
I have very rarely heard, if ever, that a sailor chooses 2 "neighbouring" sizes, whether it's a Kombat, iSonic, Evo, etc. My opinion is that a wider "spread" (but keeping some small overlap) will cover much more wind range.
