So in that ballpark you could do a lot worse that checking out Shipley Glen it's roadside, and you can pack in tons of mileage on quality rock, along with some classic lines. At those grades Manson's Wall, Phil's Wall and Red Baron would be a good day's haul.I'm sure Will be along in a minute to tell you to get to Ruin Bank Woods - check out the Unknown Stones site for a downloadable guide.I'm based nearby-ish, hit me up if you want some company / pad / spot!
If you do head to Widdop then just down the road is Clattering Stones. The main wall there is North facing and stays in the shade, with a bit of a breeze conditions should be decent even if the air temperatures get up a bit.
