I think there should be a narrow face & large nose support group! I have tried so many masks with the same problems that you and many others have reported in the past.
If you don't want to carry a regulator around, you can take a backup mouthpiece if you have one; that's what i do, always try a mask with a mouthpiece. Of course, if it's identical to the one on your regulator even better.
As for specific recommendations, i'm not sure they mean much since no two faces are the same (unless you are a twin, in which case ask the other one!) but my salvation has been the X-Vision mid.
Another issue that i have is that my face seems to have a very narrow range of mask tightness. A little too loose and it leaks, a little too tight and it leaks; maybe that's also the case with you since they fit OK in the pool but not UW.
One last question Steely: you say "constant bubbling" which could indicate that you exhale out of your nose which would obviously affect mask fit. Do you think that might be the case?
