Anyone had the chance to try the Sherwood Oasis Reg? I have the Sherwood standard octo and was wandering about the Oasis. I Emaild Sherwood to find out if it was a balanced or over balanced reg, and they haven't answered my E-mail. My LDS couldn't help me either. My LDS has them on sale and after looking around on E-bay they are cheaper at the LDS, considering new, warranty and service. In their product info they mention warm water, How warm? Where I live we dive in 55 to 70 degree water, I'm wandering if the Oasis would be a good choice?
