Worth adding a few more comments to Davy's summary. Firstly, it's not clear whether or not you have the guidebook, but the Logbook description of the "East Face" combines routes on two major and one minor crag, at least half a mile apart, and with bases separated by around 500 vertical feet. And the routes are arranged pretty randomly between them. Secondly, The Wabe should be on any list of best V Diffs in the country. But don't leave a pack at the start unless you've worked out how you're going to get back to it! And thirdly - a bit esoteric, but there are comments about the rock in the thread - the Mome Rath Face is composed of a very unusual rock for Glencoe. The main vertical height of the cliff comprises a sill of the "Upper Streaky Andesite", which gives unusual pocketed holds. This is sandwiched between layers, both top and bottom, of ignimbrite, formed during pyroclastic volcanic eruptions. (For anyone really interested in Glencoe's geology, the British Geological Survey's bookshop has a superb 120 page book and accompanying map.)
