I'm mostly confused right now with the techniques. In order to go up a rank in your school you have to buy a kata with a higher level prerequisite.  I'm assuming that this means you begin at the level on the left of the advancement guide and work towards the next and the kata should be the last one purchased as you then meet all other necessary prereqs or do you buy it to advance, and simply can't use it outside of practice until you attain the rank, thereby explaining the need for the school rank.  It's a little vague in there and open to several interpretations.<br/><br/>It seems fairly common from what I saw while looking at Crane clan pics so go ahead Andy
