My two pence worth
If i was you i'd stay away from the Proteus. I own a pair and have found them to be badly made and not really all that comfortable. The Invisions 03's (I think i've tried Mark Toy's above) i found to be very comfortable but i couldn't tell you about the lense changing. Overall my next pair of gog's will probably be a pair of flex 7 again. The new ranges look pretty sweet!
Cheers
Ken
