the smallest sails i found where ezzy sails ... 2.9 in their 2007 collection if i remember correctly. They work with a 340 mast. I never found anything smaller but seeing as the evo carries like 2.6 sails with it's smallest volume i suppose there must be. I never fonud any in any case ... maybe just eat a lot and add some weight to your body without having to sink so u can compensate or something, you never know, it might work.
