Superlight Offset Rock 5

They are light weight, versatile and and allow for placemnts in shallow features, and when you need this, it comes as a great relief. I would say the offset profile is OK, but I prefer my DMM alloy offsets every time. Sizes 5-9 have slender wires (where #10 is thicker) and this makes careful manipulation of the nut (esp sizes 8&9) pretty challenging at times, especially on a 'hard' lead. The shape of WC rocks is great, but given that the corners are not overly rounded, this wire manipuation/flexibility issue is perhaps made worse because of it. Similarly, cleaning these can be tricky when the wire wants to bend a little too easily. These nuts work very well in smooth and fractured rock and place quite well in highly textured rock. In highly textured rock you can find a stable placement by slipping them easily between nubbins, however I would say it's easier to find stability with a Wallnut in this instance. Many climbers love these for their low weight and bulk, but 9 times out of 10 I would prefer a nut that's quicker and easier to place.
