Thanks so much for the replies! I don't know what it is about the snake section, but you guys are so helpful and friendly

Good eaters? That's good to hear! Seth, my milk snake has been a problem eater ever since I got him seven years ago. He's always been underweight and has wasted many a mouse!
From all the care sheets I've read it sounds like these pits are pretty feisty, but I'm up for the challenge of taming and would love a snake with more personality (no offence to Seth!).
I was going to wait a few years for a pine, but the more I read up on these snakes, the more I want one nowwww. (or maybe a young male and female to breed in the future). I didn't even have the room for more vivariums, but I've found a way I can move around all the vivariums to make it work lol.
I think I like the Northern pines best from what I've seen so far. I think I'm drawn to medium-sized snakes with round pupils. Black pines are especially gorgeous, although the normal colouration is really nice too. I think I'll aim to get a species that grows 6ft-7ft as my milk snake looks like a shoe laces to me nowadays (though I still love him to bits! lol)
