[cypher]

The mamble is quite a lot bigger than the HH, it's a really nice size overall, has good bar spacing & good access, the only real downside is that it is very tall so you have to be very careful with how you set it up to avoid falls either from levels/shelves or bar climbing.
I find the HH a bit small, it does have great access doors though & again bar spacing is good, a lot of people find it better to use it without the tubes & penthouse though as they can just cause problems with hams sleeping, stashing food & peeing in them, not good!
