Thanks for the replies so far.
Handleability is definitely a priority for me. Originally I was planning to attend the Daytona show where I hoped to be able to see and handle more snakes in person but as it turns out my parents are coming into town that weekend and I'm not going to make it after all which is leading me to rely more on online pics.
Feeding isn't normally a problem with Bloods as it is with Balls so I'm not too concerned on that point. I also have not heard of any difference in attitude between males and females but it is true that females tend to grow a bit larger than males. For one or possibly a couple of snakes I don't think the size difference is going to be that big a factor for me.
I think perhaps my best bet at this point is to visit one of the breeders in person who is located about 5 hours away. This way I can see and interact with multiple snakes in person to try to pick out "the right one" and I know he has several that I'm interested in from their pics. There is another in South Carolina that's about 4 hours distant but they seem to have a much smaller number of available animals so I'm not sure if it would be as fruitful.
El-Ziggy - You're spot on about too many cool snakes and not enough space/time/money for all of them. In a perfect world I'd also like a boa, maybe a white-lipped python if I can find a friendly one, and a couple of others. Over time maybe I'll eventually get some of these too but one day at a time right?
