I can tell you for Ontario you'll need almost a full range of sizes and if it's for winter you'll get to use your smallest a few times but not much
outside of that - overall more medium to largest are used far more frequently.
So much depends on conditions and what you want to do and even on the same day the guys of same weight might be using different sizes depending on
skill etc.
Arcs i use everything from 6m to 22.5m
other depowerable foils from 5m to 12m
again - you are welcome anytime to come out and have a go on various styles and sizes
