I out off racks for a long time for alot of my own personal reasons. Started with a tank, then upgraded to an AP T8 then eventually 2. I'd have hit and miss issues with sheds (one in particular), snakes go off feed and issues getting them back going. They've been in their rack a month now and 4/4 feeding off tongs with healthy feed response from all. If on the fence at all just make the switch, your snakes will thank you!*
*Other methods work and can work well, just sharing my personal experience for those researching.
