Thin crimpy and techy.
Rock is limestone but is covered in little crystals so it's more like what I expect granite climbing to be, crystal crimping stuff. Dries very fast, doesn't seem to take much in the way of seepage. Good moves.
I've done the harder and I thought better of the 2 7bs there, Living Dead - runout start, then a hard bit, then a ledge, then a sustained section which gradually gets harder until a crux at the top. You'll probably find you'll want that clipstick of yours for it - the bolting is at old school in that whilst the hard bits are perfectly protected the easier ground is a bit more runout.
I've tried the easier 7b, Chiming for You, which is relatively easy (6b+?) up to a hard crux at the top, probably harder than anything on Living Dead although I didn't really work it out so can't say for sure.
There's also some E6s that you can throw a rope down quite easily, one of them (Jimi Hendrix Experience) is sort of quasi-sport in that it's got a lot of fixed gear protecting the hard bits, including 2 bolts. That one is about 7b+. The easier one is more pumpy I think but easier, I've not tried it though.
There's not much sport that's easier than the 7bs though - maybe a 7a or to on the left but they're a bit less sport (ie runouts where it's easy then you hit bolts and it becomes a bit more like sport) - see logbooks.
