I enjoyed Llandegla, but did it on a 100m hardtail (jump bike, about 4 sizes too small), not sure if it’d be as fun on my 160mm fs.
Gisburn is a giggle too, miserable weathwer every time I’ve been though! not been since the new stuff has opended though.
Like Hamsterley. Only been once but can’t wait to go again.
Really like Stainburn too which is good as its local, just needs more of it….
Oh and Whistler and the Alps are OKish as well, not limiting to the UK. 😉
Seems I’ve not really experienced bad TC’s but then I havent ridden Dalby.
