Well, technically speaking, wording in ICAO Doc 8168 includess the word shall, so it's a strong obligation.
1.4.1 The entry into the holding pattern shall be according to heading in relation to the three entry sectors shown
in Figure I-6-1-2, recognizing a zone of flexibility of 5° on either side of the sector boundaries.
However, practically speaking, I'd choose the simplest entry (lower workload) with the smallest turn (less chance to deviate outside of protected area).

If I understand correctly, inbound course is 180°? In this case you are really on the limit (sector boundary + 5° flexibility). Why would you want to complicate your life by picking (since you are within +/-5° from the sector boundary, you can pick the entry) the more difficult entry of the two? And by the way, if you are above MSA, you can do just whatever you like.
Keep it simple, stupid. Works every time.
