Is there anywhere in the UK that has juggy, overhanging low/mid grade sport routes?
i.e. the equivalent of the easiert indoor routes on the main overhanging wall at Leeds Wall / Big Depot (and probably loads of other indoor walls too).
The answer is no, sadly. There are lots of good crags in that range but they aren't steep and juggy. Presume you're in Yorkshire: Castleberg is good, as is Moughton Nab and Robin Proctors Scar at those grades. Expect technical climbing though.
Don't get too excited about Filey, there's a reason that very few people climb there! Not sure what state the bolts are in, we just did some of the trad on our only visit.
