You're right, I didn't. blush Only had a few minutes to scan the newer posts - stupid work!

Now that I have, I see that making the universal-fit SuperGnat requires that you also have a Superfly available (i.e., buying a Superfly or buying the valve as a replacement part from MSR), which could take some of the shine off the idea cost-wise. However, if you were going somewhere that universal fit was absolutely critical, cost may not be an issue.

Neat idea.
