I was there for the first time a couple of days ago whilst visiting family in Manchester (was planning to go to Broughton for old times' sake, but Rockover turns out to be much easier to get to by public transport).
Friendly staff

Very friendly, helpful and welcoming.
Loads of space/light, good temp
I founds this to be not the case, and it would actually be my major gripe. The corridor behind the comp wall seemed to have some interestingly-set slabby problems, but on some of them it was hard to tell in the near pitch darkness. Dingy white hold, or pale yellow?
In general I found the setting fun but the grading at my level massively soft. I was doing purples, some whites, and some comp and brown circuit problems that were marked around V3/V4, and flashed quite a few of them. I don't speak fluent V, but according to Rockfax V3/4 should equate to around 6B/+, and I know for damn sure that I don't routinely flash 6B/+ anywhere else that I climb regularly, indoors or out.
