I am an avid fan of the Chinto kata as well. From what I have read on it there are 2 main fersions even though I know there many slightly different veersions. one is done in the straight line some call this shuri chinto much like gunkaku. The other is done on an diagonal line, some call tihs tomori chinto and so on and so on. I have seen the straight line version of chinto and it is a nice kata but the diagonal version seems to have a better run of bunkai. Just my opinion.
