What is the most appropriate Dynamic Positioning Logbook in this case?

Good morning lads, I just got my DP Full Unlimited certificate from The Nautical Institute, from now on I am DPO Full, and I’d like to ask you guys what logbook that I have to buy to fill up my days?The blue one from IMCA or the green one from NI?
I work in a DP Class II Vessel.

Thanks in advance guys!

I don’t think it really matters, I see both used. I’m DPO through NI and use the IMCA one. I’ve renewed twice without any issues.

Don’t switch logbooks until your first logbook is full.

The IMCA book is my preference. It holds significantly more DP days than the NI ones.
