Hi, I just got a Mares Dual snorkel in the mail. Haven't had it in the water yet but I notice that the mouth piece is only in its natural position when the snorkel runs straight back under my ear. When I hook the snorkel clip into my mask strap and attempt to wear the snorkel in a more normal manner, I have to clench down on the mouth piece to keep it in my mouth. It's not a natural fit at all and I know I'd have a sore jaw within 10 minutes. The mouth piece doesn't seem adjustable so it doesn't seem like there's anything I can do. Has anyone else noticed this? Any thoughts? Thanks.
