I'm guessing 2600# for 500-550 CI, less the 175# BOPA break, less 100# if conventional heads used.  Either 2425, or 2325.

Scott Rex or Jack Gaydosh would be able to tell you for sure.

Darrin, the conventional head rule is already incorporated in the BOPA break. I guess its kinda 100 for conventional and 175 for BOPA heads period.
