I think the ball bearing grip you guys are talking about is the Van Handle Death Grip. Not sure if they're still in business though, 'cuz the link to their website seems to be dead.

Im not sure how companies can claim that grips are torqueless.
That's just the name. Their product description is as a torque reducing grip, not torque eliminator. It's at least a reasonable claim, unlike the BS you see with most bowhunting marketing.
