Do it like we do in Canada it is very simple. I ski MM or my age division all year (34mph) but just before Nationals I train at 36 then I compete in Mens 2 and or open. I can opt up to a harder division, why not who would care if some old guy wants to compete against the best. It is not hurting anyone and it lets the old guys ski 36 if they want to with the same scoring as open????
