I'm not sure what his is really, but he surprised me by coming home with it after I got off work the other day. He has a well...its all from vapor kings in Tulsa. It says DCHV 1.5 on the tank. *shrugs*
The guy suggested RY4 at 24mgs, but I got him started on Captain Jack at 24mgs and he literally threw the pack of analongs away right then in the store. I am so happy!
