Today Sean Mercer & I met up to climb Slanting Buttress Ridge Route on Lliwedd. It is a 700 foot Diff mountain route with some quality climbing and a real feeling of exposure. We soloed the first 3 pitches or so, then roped up and pitched the rest, alternating leads. The crux moves seem to be at around the halfway mark, when you take a bold step out left, overlooking Slanting Gully then move up a fairly featureless slab. However we managed to go slightly astray from the guidebook route on the second to last pitch, and I ended up leading an approx Severe grade pitch which felt hard.
An all round good mountain day.
