Yep I do kata, slowly with "perfect" technique and real attention to detail, as well as a full speed, as well as completely relaxed just to run through the moves. All good in their own way and all add to the experience. I also look at quite a lot of Ian Abernethy's bunkai breakdowns and explanations - after doing a couple of seminars with him - to me understanding the move in a variety of ways makes it more real than attacking multiple ninjas from multiple directions

and they're pretty good on youtube.
Never done the 100 kata (not sure either me or my knees would want to) - PS what's renzokuzukigeris I know geri as in kick and zuki as in punch - but not familiar or maybe just misreading it all together.
