I end to agree that it depends on the situation Moley

...strange that seems to apply to most of Shotokan as well....
...o.k. I'll start the ball rolling since I was hoping to get some discussion going - in the "Kata" scenario I tend to favour concentraing on the Gedan Barai - treating it as an Uchi (like I tend to try with most of my blocks - who was it that said that your intent with your "block" should be to demolish your opponent ?) so I go for about two thirds "effort" on the Uchi....
....now if I was throwing someone......
