Challenge? no Jools, IMO Oulton is by far the best circuit in the UK, luckily on my doorstep, but if it wasn't I'd make damn sure I'd go a few times a year, closely followed by Donny.
Conditions, not really, just don't think it's worth the trip to a circuit that isn't any better than Oulton and has very poor facilities.
What many forget is that from London Oulton is actually closer than Cadwell
