I would definitely say JCP. They're perfect.

As far as feeding goes, try to get them on rats as soon as possible. I have a JCP that made the transition nicely. I have one huge Coastal Carpet that eats big jumbo rats, but I have a coastal female that still will only eat mice. Feeding for her means a big huge pile of mice. Pain in the ass for me.

Coastals are nice too. But JCPs are really great.
