I'd say wait till you lear those 11 katas, it should take you some time to learn them, and mayby after this time your instructor will rearn new katas and teach them to you. I know about 6 katas, and I tell you, I still need much time to make them look as they should, so dont wory about the quantity. And I would like to know what are those 11 kata's we are talking about? And what rank are you?( I dont need it for discussion, I'm just curious:))
