In reply to jkarran: TOTC is probably the easiest E5 that I've climbed on grit but I think that it still warrants the grade (just). The gear is good and you can stop and rest to place it and you can also pause higher up on the arete. The last move will definitely focus your attention if you try it onsight, though it is not especially hard for 6a. You probably won't deck out if you fall from up there but given that it is a bit dynamic, you will have to have a bit of slack in the system, so you'll need an attentive belayer to make sure that you stay off the floor.
I would definitely recommend trying to onsight this, rather than top roping it first. If you're not ready for it at this stage, then I would save it for a good day.
By way of comparison I climbed both this and Elergy on the same day and I thought that they were almost worth same grade, though I was probably more physched for TOTC and the Elergy slab was a bit damp and gritty.
