In reply to Kingfisher:
Thanks very much.
Oui Oui; you suggest buying a "better" jacket now if planning more trips. We are indeed using Mera to find out if we "work" at altitude and assuming that we do, the plan is to then tackle more challenging trips in the future, hopefully building up to Cho Oyu in a few year's time.
I know that the ideal Mera jacket wont cut it on Cho but there is a world of challenging climbing at ~ 6,500m. When you say "better" do you think that the ME kit isn't that great as is more of a "budget" item?
Radson; fantastic picture! An easy 5* job! Beautiful. You say you used MH Sub Zero. As far as I know they produce the Below Zero (1050g) and the Absolute Zero (1340g). I assume the latter is a real 8000m job and yours look more like the Below Zero? Maybe it used to be called the Sub Zero? The ME Annapurna (1200g) suggests an 8000m jacket, but their next one is only ~ 750g and that seems very light for 6500m?
Oh, no, I'm not a dentist!!
