Great post David. I will pm you for more info. Please be sure and let me know if you get over here to dive again. My email has changed to cindyb3007@yahoo.com I lost your email when I moved into a new place. PM me please and we can play catch up. I also want to interest you and the CDG in participating in the Cave Diving Museum and Library. There is a growing interest in sidemount and sump diving in this country and you guys are the experts in my book. Cindy Butler
