They are lovely tank set ups and the Twilight Chinchilla items are fantastic. In the Uk we get envious of the affordable tanks in the US and Canada! They are massively expensive here. We have the Germans and Belgians to thank for our good cages mostly lol! (Skyline and Savic).
I agree with Cypher about not changing things round. Our hamster gets freaked if things move an inch. It's true they can get in a rut, but I find adding something new can help with that, without changing the basic layout round - it must be disorientating for them changing things round. They scent mark in the cage to find their way around usually as their eyesight is so bad. If I add something new he inspects it and then either gives his approval - or doesn't! I get stampy feet and looks if he doesn't like it
