No problem.
I didn't have the ladder/pads in the hole, just 2 pads covering the block you start off (assuming the same as the yanks) and an extra one on the block behind I thought I might smack my head on. I was intending to put a lid on but thought it would annoy me so swapped the helmet for a pad on the boulder. (add that into the UKB E grading science algorithm!)
Comparing The Promise to routes of similar grades I've done and in the style I did it in I felt it definitely justified E8 (and probably right at the top of the grade) in terms of E for overall effort (which is in reality all you can do on headpoint). If EOTA is benchmark E8 (and its been that for c.22 years and no-one's really argued) then The Promise felt harder in terms of E for effort. Comparing the two directly (and for the record I've done both in very similar style) they are at opposite ends of E8. And as its a direct comparison then the same applies within reason to the theoretical onsight as there's nothing hidden in either route. Both are sequency, easyish once you know how, gear is not tricky to place, possible injury etc
Doing it with so many pads/ladder covering hole etc then maybe it would feel easier but I'd feel a bit bold and dare I say it inflammatory giving it E7. But, I didn't GU and Pete has way more experience in the lofty grades than me.
Had the gear been kicked out on one of the GU ascents/Jack's attempts would we be having the same discussion? E9?
Comparing it to superstition yeah its not E8, but given that (AFAIK) no-one but Miles can even do the damn thing top rope or no top rope would anyone be arguing with superstition getting E9 or possibly harder? Same goes for superbloc. All it does say is that its desperate to grade all these bouldery, potentially dangerous, super highball routes.
Anyway, it looks like I've just walked my way into a grade debate I didn't much want to get into. I do think The Promise has got some awesome moves on it and I really enjoyed climbing it. So thanks to James for putting it up. I'm just hoping nobody spanners themselves in this craze we've got going on. Take care out there and for God's sake enjoy it.
