My outfit uses either Std n-1, straight ahead speed-up/clean-up @ 1500ftAAL, or E/O SID
if option 1 is not possible due terrain .We are not allowed to use the E/O SID from the database (MD11).But I think a SID is your best option
when in doubt, or when you've passed your first turning point.And I really get the impression that ATC doesn't know about E/O SID's, so get on the phone early....
