Help with nightforce one piece or rings for Howa 1500

[Boxerdog]

I am looking for some help and advice for my Howa 1500 heavy barrel rifle in a Hera stock. The rifle will be used for a hog/ deer / target rifle and as a trainer for better hunting marksmanship. I get a really amazing discount from nightforce so I am wanting to go with them. I can’t decide between these two mounts, I only have experience with Dnz one piece mounts when it comes to these types. I have calculated ( I did read the sticky on ring height) but I assume I will need high rings. Thoughts opinions welcome. Thank you
