It's called the Ultimate "Twister"........I just finished installing one on my Liberty.
I'll have more later when I can put it through it's paces on my personal bow, but I can give you a few highlights.

Like Jeff said they were on a few of our bows at the ATA show and the rest worked terrific after getting brutalized for those few days.[]
I was impressed enough to get one and try it for my own use.

Full containment is VERY nice feature......I have a tendency to be like a bull in a Chinashop when I reach for my bow as a deer approaches. The arrow can't go anywhere.
Seems very consistent and well built, and tuning is very easy because of some adjustable settings for cord length as well as spring tension and windage.
I'll give eveyone more details as I discover them with it, but so far so good.

I liked it enough to remove my TT Shakey Hunter that was shooting very well for me. As a hunting rest I just could not ignore that full containment feature.
