This chock is expensive and well worth it, the shape is easy place, and smooth to remove, I've found it particularly nice in granite placements as the curvature finds nice hold on the crystals. That said these excel on any type of rock. They are lighter then any other nut too! which is great because we all need to lighten our rack up. If your into free climbing and not aid then the non swag configuration should not be a problem as your most likely to encounter bolts without hangers while aiding. These nuts are awesome and Metolius' quality shines through once again in this product.

the curves make it bomber placements, but it also makes it hard to remove! i bought this to replace the one left in the wall. (belonged to a friend's rack). i personally have the BD stoppers as they are easier to remove and just as easy to place.

I love the curved face. It makes placements super stable.

Bomber placements but hard to remove.

I like these new nuts by Metolius. They eliminated the swag on the old style nut. I am hoping this will help eliminate the kink that is common on nuts after a difficult removal?

While in J-Tree last winter, I used a friend's set of Curve Nuts, and I was very impressed with how easy it was to get good placements with them. These are way better than the BD Stoppers, imho. Everyone and their mom (and me too!) has Black Diamond gear, Metolius makes great cams and passive pro too!
