Intake has a range off routes in your grade, if it is a decent day go on Darkness Walls, loads of amazing routes in the grade. At 6a El Sergio is the route of the crag, but a 70m rope is essential.
Slaley may be on the harder end of your range.
If Harpur Hill try college buttress since Gary cleaned, added and re-bolted.
Go on Gary's site and look for what suits your aspirations. There are plenty to chose from.
Horseshoe is best avoided, especially at weekends.
