IMO, dont, you will not like them after having RBI racks. They are far to open for me, the one I had, I had trouble with heating and humidity/sheds. Ive never had trouble with sheds with RBI though, because of how enclosed they are.

Im not sure, but I also think Vision racks are more so for people with temp controlled rooms, or keeping them in a room that says warmer than normal. They are so open, that I also had trouble keeping my room at a temp that did not make it impossible for the heating to work good with the racks.
