A few Qs about RBI racks.

[starmom]

I use RBI 32qt for adult males and females up to 1500g, once they reach 1500g they go into a RBI CB70.

Get the 32qt for now then you will need to buy a CB70 later down the road.

I use belly heat on both.

I agree. I have 2000g+ females and the 32qt is just too small for them. I also have a couple of larger males who are outgrowing the 32qt.
