Hey,
I think that as with any species of snake you plan on working with, there is going to be some level of a learning curve, regarding what works and what doesn't. Of course, you don't want to start out making mistakes only to wind up with an ill snake the first few weeks of owning one. However, in my opinion, for what ever it is worth, bloods and short-tails, can to some degree be described as a "Non begginers Snake". Although, what can also be said in your favor is that you have some experience working with quite a large group of BP's. That counts for a lot IMO!
Do the necessary reading and ask all of the necessary questions. Talk to as many people here on the forum and get as much insight about the particular species, you're interested in, and I'm sure things will work out. Provided you have a good understanding of the basic needs and cage requirements for your charge, you shouldn't have any problem. I currently keep about 20 short-tails and bloods. Kara of Nerd, exceeds that 4 fold, I'm sure. At any rate, there is lots about bloods and short-tails that sets them apart from other python species i.e. Retics, Burms, and the experience is rewarding once you understand the needs of your blood and or short-tail.
Have fun! and don't be put off. They are amazing animals.
