I also live in Ohio and I can tell you I prefer the AP T-10 or equivalent.
You can raise ball pythons perfectly fine in rack systems from hatchling to adult and polypropylene tubs are amazingly easy to clean, but I do not believe them to be ideal "end of life" enclosures for ball pythons.
My reasoning -
Rack systems are very easy to use in conjunction with heat tape or UTHs, but they are rather poor (as a previous posted mentions) at increasing ambient temperature. This means they work well in a room heated to 77-80 degrees, but (in my experience) poorly in rooms normally kept at lower temperatures. Also, I am of the opinion that ball pythons use the extra space in a 48" enclosure. They are seldom active during the day, but ours are quite active at night, even more so it is nearing feeding time. As with humans, a little exercise is probably good for them, but I have no scientific evidence to support this in ball pythons. As another consideration, our larger ball pythons use the
extra large hide boxes often used by ball python owners. These hides do not fit well in CB-70 or equivalent tubs as they are too wide. When you move up to something 48" long x 24" wide, you have a lot more space for two of these hides and water dish without taking up 100% of the usable space.
T-10 and other plastic caging (in my opinion) really shines when used with RHPs or a combination of a RHP and UTH. RHPs, while not as good as heat lamps at raising temperature, are quite a bit better than UTHs. Ours are able to raise the ambient anywhere from 7-10 degrees as well as provide hot spots. That said, you could use an RHP set to a slightly lower temperature in conjunction with a UTH and achieve potentially better results depending on individual circumstances. I personally prefer the T-10s for two reasons: (1) they give you a little more height to work with during cleaning and "snake wrangling" and (2) When using RHPs, if your enclosure is only 12" height, you are rapidly loosing height to work with. Also, I think it is really easier on the snake as it is further away from the heat panel and when swallowing food, many snakes will "rear up" to assist in swallowing. I notice some of mine getting cramped or hitting the ceiling when in shorter tubs and enclosures.
Alternatively, if you are heating the room to appropriate ambient temperatures, a T8 with solely UTH heating is still a little short for my liking, but probably perfectly fine.
