I would think the string would slice the stopper right in two. There is a slow-motion video running around of one in action and it appears to take one heck of a whoopin' from the string.

Have you served the string yet where it hit's the stopper?

I ended up adding a string leech on the top of my Tribute's stringand feel that it made the bow even quieter than before.

For grins you can just rotate the STS out of the way for a few shots to help compare.
