I use a 12m Kitech FRS Ultalight with 21m lines as my biggest freeride foil kite with a Groove skate small or KS 37". I weigh 110 kg. I can ride this setup when I can't get going on my 17m R1V2/racefoil combo. The 12m Kitech Ultalight is a crazy good kite. Turns MUCH faster than my friend's Soul 10m...
