5000 meter height gain

We can get our 5000 meter gain here in Oregon without ever going above 18K,
come on up. We also have a window if you want to go higher. See this
month's Soaring magazine for my story about our wave.

And about the M&H system, I use the cannula but you have to be very careful
that you don't take any breaths through you mouth. I've heard of some guys
holding a mouthful of water to make sure they don't. Carl D. Herold did a
lot of testing with cannula use at high altitudes, he is a great recourse
for any advice about high altitude soaring.

How do most pilots go about the 5000 meter height gain in the Sierras?
Somehow getting in a glider on a cold/windy Minden winter day does
not sound like me. During the summer I stumbled across a wave
condition behind Mt Rose but I was not sure about how the O2 system
worked and where/whether the wave window was open so I stopped short
of 18k If I was ready this would have been a perfect opportunity.
Seems difficult to know when these conditions will exist.

Another question is if you use the M&H O2 and you are staying below
24k do you use the cannula or the face mask? I think I know the legal
answer but it seems that the cannula is actually the preferred option.

Any advice would be appreciated.
