Christmas is a-comin' etc. and I'm thinking of replacing my old A14
diluter
demand system with a Mountain High EDS system. The A14 hasn't been used
for
years; now I'm living in the mountains I want something I know I can trust

Can I trust the EDS system? Anybody out there got anything good or bad to
say about it? Should I swap my old steel bottle for a new one - if so,
aloominum or kevlar? I like the idea of the canular - is it reliable?

EDS is good, a freshly overhauled A-14 is better.

With a good mask fit, the A-14 will keep your blood oxygen saturation at a
steady 98-99% up to 40,000 feet. It's a safe and solid bit of equipment.
I've never seen anything that good with a nasal cannula. Also there is
cost. I hear that an A-14 can be overhauled for about $350 and the purchase
price of an EDS is three times that.

Below 18,000' a cannula is much more comfortable than the old olive drab
masks, however

Steel bottles are heavy but cheap. Aluminum and kevlar are light but very
expensive. I guess it depends on what the overall W&B of your glider (and
wallet) looks like.
