I have to agree with Zippin. Both are amazing masks, both have their pros and cons. But the more comfortable on YOUR face is the winner.
Lens on the E-Flex takes literally, 1 minute to change, if that. The i3's on the other hand... need at least 5 minutes and strong thumbs.
Flex parts are abundant, and easy to get a hold of. i3's are dwindling...
Both breathe very well, both are very customizable, both are very light and comfortable... Try them both on, which ever is more comfortable, do it.
I'd try the Proto Axis Pro's as well, if I were you.
