As one who has gone through 6 masks - only 2 of which fit right, I sympathize with you. The 2 that fit are identical. I got another one for a backup when I finally got one right. I wanted the latest greatest highest tech mask available. Low volume, anti glare blah blah blah. The one that works is the first mask I got. So much for high tech. Find one that fits your face and be happy. Just my .02 is that I agree, probable problem was hood initially then adjusting mask too tight. Good luck and happy diving.
