Well I pulled out my VCC Buffalo guide and it has Spaceman Spiff finishing as for Dead Heart. I'm certainly not saying that's correct given Kieran's knowledge of the rock in question. However if Joe was working off the guidebook then basically everything from the middle to the top of the climb would be new.
As for the climb itself, I had a look at The Crag where TINOL is 20 and two stars. If that's true I'd accept 18 and borderline one star for TDAID, however in my personal opinion, 17 and no stars, but worthwhile.
