Careful with logging PIC time with out being the PIC of record, even if you are pilot flying. As far as a resume goes, (the reason why PIC is important) most major airlines only see PIC time as being the one who signs for the aircraft. You can legally log PIC as sole manipulator, but you may have to separate it out later.

Also, does boutique have OPSPEC A015? If they don't, then an SIC is always a required crewmember.
