Just be VERY careful as to when you do not follow the SID. Some companies predicate emergency turns ONLY when the EO SID flight path is unsafe and you MUST be very sure before continuing straight ahead (or, equally, accepting an ATC 'early left-turn direct XYZ approved', etc BEFORE the donk goes), that you have satisfied the ANO and you have ensured a safe flight path in the event. As JT and others say, know the basis of your company's calculations.
My understanding is that ATC will expect you always to follow the SID unless you tell them.
