I don't know if this has been posted here before, but check out the video of boo's string. Did not know that the scope moved so much.

That was interesting. The Boo string is not nearly as animated as the first vid of an Excal. http://www.youtube.com/watch?v=rmntwlIhco4
Could be two different bows too.

Those cat whiskers are really moving.
I can't believe how much the scope moves during the shot.

Yes, I love those slow motion videos that show what happens. It sort of makes you wonder how these bows can hold up as well as they do.

It would be nice to see the same with the use of an STS / NGSS.

I suspect that the string would whap against it, remain stationary, then wait for the limbs to flex back, and then come away from it, only to strike it again. That stationary phase allows vibrations and energy to be transfered to the riser. This what I am most interested in, directing the energy and vibrations towards something that can absorb them, versus allowing them to migrate on their own over the entire bow and all it's components.

The claw releasing the string does make a substantial amount of vibration. Thanks for pointing that out. I am going to watch the video some more just to see what I can gleen about that.

Yes- you were absolutely right about the claw release. On the last shot of the first video posted here, you can clearly see the shooters hand reacting to vibrations long before the string ever reached the riser area. I doubt this is from the string riding the rail, so that really only leaves the claw. I thought it might be from the shooter jerking, but the fleshy parts of his hand are clearly folding from the forces generated.

Very nice. Thank you again.
