Hello, hmmmm i have a couple ideas..... mine are from personal experience....
I've got a Taiwan Beauty Rat Snake... they grow to 7-8ft sometimes 9... but they are a very slender snake, mine is between a golf and tennis ball at his thickest... He is 2.5 years old now and just measured at 6ft 6inches.... you dont need a huge enclosure for them either... up till now Ive housed him in an Exoterra aquarium thats about 1.5ftx1.5ft base and 3 ft tall, Im just now going to be moving him into something a bit bigger.
He is a fairly active snake, aside from when hes shedding or recently ate, mostly meaning he doesnt just sit there forever and look dead like you mentioned...
My personal snake is great for handling, he does like to move around a bit, will go into your sweaters wrap around your neck waist arms haha... even climbs up my head a lot. It does take a couple mintues to get him into and out of his cage because he is so long and its a very rare occasion that he is not wrapped around something lol. But other than than that he's great.
As for eating, my snake is a machine, and its very wicked to watch him eat! At his size now he is taking about 5-6 rats that are around 3-4inches long. anyways, not sure if that sounds like your cup of tea?
sorry to get into so much detail ill try and keep it short with the next two. I also have a black mexican kingsnake, they are a rather cool lookin little thing, solid black head to tail... they dont get huge mind you, maybe 4-4.5ft.... between the thickness of a roll of quarters and a roll of loonies. hes rather active too. i do have a rock for him to hide in and he spends a fair bit of time in it but if i go up to his cage he 99% of the time pokes his head out or comes out and does a lap or two around the cage. these snakes are known as nippy but i havent noticed it too much, I just got bit for the first time by him the other day and had i not been looking while he did it i wouldnt have felt a thing. Hes nice because hes not nearly as muscular as the others and so is generally easy to keep and hold of and direct and will just sit in your hands. These snakes are also quite vicious eaters and interesting to watch.
Lastly I have a ball python... these snakes are more like teddy bears i think. They get to arounf 4.5ft and vary in thickness but there are LOTs of pics if you want a better idea. I can sit down on my bed/couch and put the snake on my lap and not really have to worry about losing him for a long time! pretty slow moving and laidback snakes.. They also give off the look of a bigger snake with there thicker heads and bodies. The only downside with these snakes is they are finicky (sometimes seasonal) eaters.. if you have any more questions lemme know!
