The DMM Wallnut is a superb nut for nearly all types of climbing. I've used these in gneiss, granite, and limestone.

The thing that sets the Wallnuts apart is a longer shape, that tapers differently with the sides being more offset. This results in a variety of more useful placements. Practically speaking these offer more secure fits in a lot of spots compared to simpler nuts. I've got a set of BD/Grand Wall nuts I have compared them with side by side. 

The other perk is that the Wallnuts have a deep groove in the middle. This has a significant benefit especially in granite where this allows the nut to be placed despite awkward crystals, or even use small bumps as a means to stop the nuts walking. It's one of those things that until you have it seems frivolous but then feels disappointing whenever a tool doesn't have that feature.

They are a little pricey and it's a piece you seldom want to leave behind. Also the smallest size is still pretty big.

Best stoppers on the market. Really. Great placement, retrievable.

Use 'em enough you'll see the difference.
