Clicker is semi contact (which can be an interpretation problem) and allows strikes to the top and sides of the head so it gets you blocking your head and keeping your hands high - I am not going to debate moderate knockdown vs Clicker as I think they are both valid ( and I have never done moderate knockdown so can't know if it works as a training tool). But I just think in Clicker you're leaning a different skill set from water down knockdown as I think in any knockdown there is a tendency in lower level comps (especially kids) for it to be more about aggression and brawling than technique and learning a fighting system - but as I said I've not done it/ been taught it so I can't judge from anything more than I've seen on the Net etc.
