In my outfit, we fly all SIDs in LO BANK, since these assume 15 degrees angle of bank turns (as usually noted on the Jepps). As soon as we get radar vectored (such as taken off the SID with direct routings), we switch to HI BANK, since ATC expects rate 1 turns. That is of course,
provided we have white bug +10kts in normal conditions, or red bug +10 in icing conditions. As for PAX comfort... we fly cargo.
Remember that even in LO BANK, the AP will in LOC* make turns with up to 30 degrees angle of bank if required to intercept the ILS.
Cheers
