I recently had a chance to try an ocean reef extender mask and the OTS Spectrum in a pool dive. I was experiencing the chin slide with the spectrum if I moved my jaw around while diving. From other posts that can be adjusted with the strap settings.

The other issue was at roughly 6 feet the soft rubber of the mask seemed to contract in around my nose to the point I had trouble breathing from just my nose and if I exhaled through just my nose I could almost equalize without having to pinch.

Can that be adjusted with the straps or is it going to be a face shape issue that would require a solid frame FFM?
