Rubatex might be okay. Ever since the Profile XPM series started I would consider those as well. The Concept was the most comfortable mask I've ever put on, but was out of my price range.
If any of the custom mask makers use something similar that would be awesome. I just can't do the foams the old Profile series used (or any CCM or any Vaughn mask for that matter).
Anyway, I really didn't mean to derail the thread. Back on topic!
