I have recently started training on the Diverite Optima, and my unit is BMCL. I tried the OTSCL configuration and it seemed very awkward and "crowded" for me but the BMCL suits me well. My instructor has MANY years on the unit with OTSCL but none with BMCL. What is the proper procedure for doing a dil flush with BMCL? Doing the "arm cross and crush" method won't work for me. Should I be vertical, horizontal? listing to "port" (left)? Any help would be greatly appreciated.

Thanks!
