In reply to caver:
I was also at castle, leading, last weekend, and at vauxeast a couple of evenings in the week.
Castle was very quiet and pleasant, I think it helps that they've split into lead/top/auto/bouldering spots. They're restricting numbers or area too, which works quite well.
VauxEast was good too. It felt busier, but I think mostly because people weren't climbing the comp set in the middle as much as the rest. There was no problem finding space if you wanted it though.
