In reply to MikeR:
The Bhasteir Tooth by the easiest route would be Collie's Route. It's a long diversion, and it is quite obvious when you're actually at the toe of the buttress. There's a good photo of James Roddie's on UKC that I used, which shows the ramp and face features clearly.
It's accessing Am Basteir from Bealach na Lice that gives the easy walk around to the north. Accessing the Tooth from Am Basteir is more difficult, but I reckon ascending from the Tooth to Am Basteir would be easier, with the soloing crux being one short tech 5b 'boulder problem', which is not really exposed.
Never done the gully out of the TD Gap, but pretty sure you can. I saw a couple guys doing this when we were on the Severe.
