A real head scratcher !!

Yes tree98 don't worry about guys giving you a hard time about legal stuff. Continue asking questions. It's good to be aware of legal things but every one of them break the law somewhere. I personally like when a guy will share openly what they try, legal or not. It helps people learn what is possible not what they are told is possible.
Now definitely look at those rollers as a safety issue though. They look like they won't have any longevity for staying in the retainer clips and probably will fall out on you.

I got busy yesterday but this is what I should've posted. From the picture you posted which is not a great angle, it appears the rollers are riding off center of the s-cam. if my pic is correct, I'd take a good long look at how that s-cam is mounted.
