I have played around with several different masks over past 3 years, and to be honest I cannot say I've been happy with any. I would say I have a med to large roundish face with a slightly large nose. The most common place for a leak is just to either side of my nose on the crease where a moustache would be if I had one. So far the closest to a good fit are omer alien blackmoon and an apnea spearo, cressi masks tend to be poor fitting for me. Any recommendations please for a good all round spearo mask. Thanks.
