I not sure what you mean by activations.
"Strike activation", the mechanical vibrations of the staff when it strikes something?
That's it, but I never strike at anything physical only in the air as shown in my videos:
The activations are harder to see when the staff is immediately 'bounced down' and returned from the asymptote but if you look closely it's visible. These were made with grade level 3 and 4 hickory. I've been training with grade 7 now for the past six months and it's completely changed my practice. As I mentioned the higher density wood can carry frequencies several times that of the lighter density wood.
