I think - most people here either are rack or aquarium people - I don't think there are a lot of cage people here - I may be wrong - but it doesn't seem like there are a lot of people that use those for balls - may be why you didn't get an answer. I have an arboreal cage for my GTP from herpcages that I love but can't tell you one way or another on any of the others - buy whatever you like best - I beleive any of them will get the job done.
