I have mixed views about Kanku Sho.
Negative:
It is another kata to learn at a crucial point in my preparation for testing for shodan. I have a strong feeling that I don't learn kata at all well enough in progression though the kyu ranks. Also Kanku Sho has some pretty athletically demanding moves (eg the spin and drop) that I struggle with.
Positive:
I like learning new kata, and Kanku Sho is demanding. I would like to stick with it because of these demands (does this make sense?) just to "set the bar higher".
I also like the damn thing 'cos it incorporates a lot of the heian kata stuff, so feels familiar. Lots of peripheral movement, more than in other kata i have learnt, so interesting from that view.
as I say, a mixed bag for me. Wouldn't want to stop doing it, but struggling a bit with it at the moment.
