I will also endorse the comfo bite fit. I found that Sea Cure (older generation, I have not tried the newer design which came out about a year ago which has a better air flow design) to be able to take away the jaw fatigue that I found with Scubapro regs.
Some people also put the comfo-bite on upside down and like it even better.
Also I have found Sherwood regs have a good fit, at least for me.
