Dual sided heat or Belly heat?

I am ordering a rack from Animal Plastics but was torn between getting the belly heat or the dual sided radiant heat. It's an Iris rack (hatch/juev) Suggestions? Thanks!

I use IRIS tubs in my racks, and belly heat has always worked well for me.

I don't have any experience with back or side heat.

Belly heat has worked well for me as well. I think that's the general consensus for bps.

Yeah, for balls I would go for belly as well. :gj:
