At UKC we are all climbers and we understand the strong urge to be outdoors as the weather is finally improving. Please proceed with caution though.
5m. Go east across the track from the slab and crack and you'll see a prominent blank arete. Downhill from this is an undercut block. The arete has a short crack on its left and a flake on its right. Layback up the crack, reach round to the flake (crux, quite a bit harder if you can't reach it from the crack) and scamper to victory. A perfect problem.
