Rocks
The original Rock was developed by Mark Vallance two decades ago. It has been subject to considerable revision since and now stands as another fine example of classic Wild Country Engineering.
The unique shape is engineered to take up the most stable position in any crack, the convex side locking firmly against the two 'feet' of the concave side, creating a stable triangulation of forces. Planar side tapers ensure stable side placements and allow you to 'turn-key' Rocks into pockets. Smoothly machined edges and corners, together with the use of carefully selected 6064 T6 aluminum extrusions ensure Rocks 'bed' easily into cracks, and can be easily 'cleaned'. From size 4 upwards, the next size can be obtained simply by turning the Rock through 90°.

One the lightest made and still one of the stronger lines available. Just as easy to place as other brands. They have useful color coding on the loops and the numbers are large enough to read while they are hanging on your rack.
I really like my set and have been adding duplicates as needed.

Like them fine
These are similar to the BD and ABC nuts, but are slightly different both in numbering and sizing. I have the newer models, which are a bit lighter than the old ones.
One thing to be aware of is that the wires on the smaller rocks are spaced close enough together that someone cleaning with a BD nut tool may have problems (had that exact issue with #2). Something thinner like a pilfered butter knife or metolius freenut would work though.

Better than BD
I like these a bit better than BD's Stoppers due to the fact that they are a bit longer and have a slighter taper than the BDs. They seem to nest into a placement a bit better and have more surface area hitting the rock than others.
