Quick thoughts on this thread:
I brought up the issue of cog availability with Level, you can see their response I posted in this earlier thread.

Phil Woods are top notch, but even those can strip. Dig through Matt Chester's posts on the 9th and 13th and you'll see he's buggered one side of his Phil. But, I'm sure it has tons of miles on it and he's planning on getting another one, so that's a sure stamp of approval.

Personally I hope Level makes it. It's a great idea.
