Hello there
Im using a new Mares MR22 Ruby regulator. The first stage does not swivel and the hose is very stiff due to its high performance 1/2" bore, instead of the regular 3/8" bore. I broke the mouthpiece in less than 20 dives from biting it hard to keep it in place. Im considering switching to Scubapro MK20UL G500 if there is no cure to my problem. Jaw fatigue is a big factor for me. Any suggestions?
Best regards
Adrian
