Firmware for P8 BH

Does anyone know the recommended firmware for a P8 BH?

I recommend 7.1.4 for all the BH. I don’t intend to upgrade them to 8.x.

We have a P8 BH running 7.1.4

We are running 7.3.6 with P8 colocated with 3 5.7’s - no issues.

7.1.4 haven’t tried to upgrade… if isn’t broken don’t try to fix it…

Thanks.
