my company go straight ahead, tell ATC when we have time to do so, use a standard acceleration cleanup of 1580' qnh, clean up as required, and expect to turn towards an appropiate holding point and climb to 2300' qnh which is the local area msa.
But once you turn towards your holding fix you are not on any specific published track, I know its not a lot between 1580 and 2300 but what terain guarantee have you got whilst under the msa?
Im just thinking if there was a significant difference, say an msa of 7000ft all round.
Whatever direction you choose to turn you will be under the msa, off track whilst you climb.
If you choose to continue climb straight ahead because there was no EO sid you will easily end up further than 25 miles.
