Actually the bamboo I have is best branch. I know what you mean about it being slippery. But I went to petco/petsmart those branches are so ugly, small so expensive for something so little.
I have a bamboo forest near where I live in Richmond, most of these bamboo
has branches sticking out of them--
I will take a photo of the bamboo branch--- it has tons and tons of branches coming out of it.
They both seem to be happier since they have they're own room and they don't hiss.
Its wayyyy easier to handle them vs. them being in their enclosure 24/7 becoming too cage bound.

I do agree them being outside they get less sun-- for some weird reason my chams both
frequently go in and out of their enclosure often. They never stay at one location more than half hour.
When I feed them, the eat in the enclosure. They food stays there--- I close their doors when it's feeding time.
They are always roaming, and they seem much more less pissed then you come to handle them-- one of them will volunteer to come to me. Before they both hissed if you left them in the cage or if you try to fix their enclosure, they used to bot get really mad.
I prefer them to free range-- because I work 9-5 and having them stuck in a cage for 8 hours with light bulbs seems mean since they can come out and I have the space for it.
I got the bamboo from a bamboo forest, not from a store. Some leaves are still on it after I washed it with bleach and let it wash with water later.
The little guy goes up and down (7 weeks now) at least every 5 minutes - he loves it, when he's back in his enclosure after i tried to lock him up, he gets really dark and doesn't seem to enjoy it after he's seen what it's like to roam. They both go all the way up to 9 ft. to the tallest point.
