Thanks that is actually a really clear description, I think I have got it.

The good climbers go so fast! Or alternatively, use such impossibly tiny holds. It is hard to see and understand the detail of what they are doing. But inspirational!

I feel as though this is something I knew as a child, climbing about on the rocks at the beach, and am having to relearn. But I expect it will come. I trust that it is still in there somewhere.

Thank you for the tips :)
