Jacket has been in his new upright cage for about a month and a half now. We have been refining it during that time. Even though we thoroughly sanded branches before putting them in, he managed to scuff himself quite nicely. A ten-inch long streak on his side has bent scales, many of which are slightly shriveled, and seem to have been parted from the outer layer. No visible broken skin, but I did wipe him with chlorhexadine a few times just to be safe. He spent the next night in the bin, while we attacked the cage with sandpaper and silicon AGAIN. (Sandpaper is very good at removing urates, by the way) If usage is anything to go by, he LOVES having the vertical space. He climbs around quite a bit, and is quite active. I know he journeys all the way to the floor of it, because he likes to tip his water dish (I have been switching out different ones, trying to find one he can't tip as easily). With the radiant heat panel, his basking spot stays a perfect 90ºF during daytime hours, and cage temps drop at night into the mid eighties on the warm end (the upper half) while the lower half remains slightly cooler. He is a clumsy snake, too. His basking spots are on wide branches (twice his thickness) so he would have a sturdy basking spot. He falls, sometimes, I have seen him do it twice so far. The first time, he was on a lower branch, and I was filling his water dish. he picked up his head to watch me, and overbalanced. fell a foot to the cage floor (which at least had a good 3-4 inch layer of coco-fiber to cushion his fall) The most recent fall, was from his basking spot (probably 4.5 feet from the floor of the cage.) I had opened up his cage to do morning checks, and he overbalanced again, and fell all the way to the floor. I winced, but he was back to his basking spot in less than 5 minutes. We have since added more branches to give him wider 'platforms' to bask on, and more chances to catch himself if he overbalances.
