As a single herp keeper, I don't keep anything I cannot handle by myself. So far, the longest snakes in my collection are around six feet long and it's not a problem (carpet pythons). The largest snakes I own are short tail pythons. I have an adult female black blood and I have no problems handling her. I've given her shots for an RI (T-stat failed) by myself.
I sort of draw the line around 6 feet, depending on snake species. Some people draw the line at 8 feet. I would no problem keeping a red blood python. However, I am a short Asian woman, so as much as I may like some of the red tails, it's not something I feel comfortable working with by myself. (I'd take some of the central American varieties though).
I probably wouldn't work with a coastal carpet python, but they just don't have the appeal to me as much as the IJ's or the jungles to begin with.
