This is pretty cool, I like the idea but I don't think you can make an exact science out of it
Of course, I was just tabulating it to give newbies some comparisons to think about.
For the record, I have kept 27 of the 34 species listed and have experience with taking care of 32 of the 34.
you can't compare a gartersnake to grey banded king or burmese python to a rosy boa and get acurate results
I agree, but most people who are starting out are making those comparisons. Actually, I don't see anything wrong with your first comparison. The second has obvious problems due to the size of adult burms.
Someone who is interested in a small lively snake isn't even going to consider a python and visa versa
Have you ever kept a Children's or Spotted Python? They are as lively as most popular colubrids. The same is true for a large number of boid and python species.
For instance, for a beginner I would recommend a health established adult milksnake for a first snake, but unproven baby milksnake would be the last snake I would recommend.
I agree. I was hesitant in treating milksnakes as a group. A newborn Black Milk is a very different snake from a newborn Pueblan or worse, Scarlet Kingsnake. Even as adults, I think Sinaloans, Mexican and Black Milks make great "pets". Most of the other milks aren't good starter snakes at any size, in my experience.
Also I have to ask why you have rated ball pythons so highly when they discourage many first time snake owner because of their tendancy to fast for months at a time especially when first placed in a new environment.
This isn't usually true of CBB balls (I have kept over a dozen BPs over the years and currently have a CBB pair that are as easy to keep as any kingsnake). Wild caughts and wild bred/captive born are terrible starter snakes. In fact, I included Balls, not because I recommend them (I don't), but to include popular species. That's why I included Burms and Retics, both bad starter snakes.
If I had been a little less objective about scoring, I could have moved BPs further from the top, but I scored them as objectively as I could, and that's how they fell out.
