Usually I use Wallnuts, supplemented with DMM Offsets if I think Iíll place loads. I find rocks are better than Wallnuts on limestone though so I take the Superlights/ bigger Offset Superlights (the names are so confusing as both are offset, the real difference is Superlights cover 1-6, Offset Superlights 6-11) as the second set on long limestone pitches.
I canít say I love them really. The smaller ones have a tendency to pull straight through placements that a full size rock wouldnít and to create scary swivelling placements in shallower cracks. I might just go with a second set of normal Rocks- Ideally Iíll be in at a new address by September so it might be less faff to do that as well.
