In reply to Dave Searle:
Super useful info, thanks Dave. I had a quick peek up at the Pelerins while driving through the valley yesterday and thought Carrington-Rouse definitely looked doable, and Beyond was certainly getting there.
Surprised there aren't more reports from the GJ. A young Finnish guy called Juho apparently went up to do the Croz Spur but sacked it off as it was too dry. I think they then went over to Zermatt and did the Schmid instead? He posts on here sometimes so maybe he can offer some info.
