In reply to GuyVG:
Probably easy 7c guy. The crux bit that is necky is with two small RP's just to your left at knee and foot height. I used ice lines and had a screamer and revolver krabs on them. My max sport grade is 8a+. I reckon routes like Macleods Flocktalk or Caff's Tower at midnight are probably bigger leads and they only get E8. not sure what other ascensionists think. It's an E8 into an E7/8 so not sure that makes it an E9.
Grades are only a rough guide any way.
If Calum Muskett has done it then realistically it can't be more than E6
