RBI rack holes?

Yeah, but then I'm worried they're not getting enough ventilation....BP's health is my first concern.

Brion99, if you're holding out for the assembled masses here to come to a single recommendation, you are certainly going to be frustrated.

I stand by my experience which has taught me that if you have enough holes to maintain 50-60% in your tubs, you will have sufficient ventilation to maintain proper health in your ball pythons. I’ve been doing it that way for 4+ years using RBI racks and I’ve never had a health issue with my snakes.
