OK

I have a Cal King

A Cal King is cool, because she has calm personality and specially great feeding response
but I want something "little" bit bigger than my Cal King.

but still docile, great feeding response, controlable size(thats why i dont like Redtail Boa..because they are too big)

I did research, and i found:

1. Irian Jaya Carpet Python
i heard these guys grow around 4~5 ft, great feeding response, and has great color

2. Jungle Carpet Python
these guys are little bigger than Irian's(4~6ft), but same feeding response, AWESOME color

3. Brazillian Rainbow Boa
they are really cool, but hard to take care of....right?

what do you think?
I have 40gal breeder tank

I keep a Coastal Carpet and a pair of Brazilian Rainbow boas (among other snakes) so I can give you a comparison between the two.
Coastal Carpets (and I think the temperaments of carpets are all pretty similar)- start off nippy. I enjoy my snake, she's gorgeous, but she's not my favorite. She's always eaten regularly and calmed down as an adult. I mostly trust her when handling because she lets me know when she's not in the mood by getting huffy. Very hardy snakes in my opinion.
Brazilian Rainbow boas- beautiful snakes that tend to hide most of the day (they're nocturnal after all) and require high humidity. Of my pair, the female has tagged me once and I do not trust her most of the time handling her. The male is more relaxed and a better eater. When I first got them, they only ate live prey but I've gotten them used to frozen thawed (took a few months). You really have to watch your caging on these snakes. They aren't tolerant of the humidity level dropping or of high temperatures, especially as juveniles. Colombian Rainbows are more tolerant of lower humidity and temperature fluctuations and are a chunkier snake than Brazilians.
I have one more suggestion for you that's not a boid- Beauty rat snakes (like Taiwans). Super feeding response, get to be large adults (mine's 7.5 feet), hardy, and very interesting to observe.
Good luck in your choices- you may want to check out the forums for Carpets and Rainbow Boas and post some specific questions there.

You could look at some smaller island forms of red tailed boas, like hog islands and cay caulkers. They do have a possibility of outgrowing your 40 gallon.
Borneo blood pythons usually stay under 5 feet if memory serves, and aren't very active. Actually, you usually have to poke them to get them to move, then you feel bad for poking such a lovely snake.
Beauty snakes are cool but an 8 foot Taiwan beauty will not be happy in a 40 breeder. I'm building mine a custom cage. Chinese king rat snakes are worth looking at but they don't all have the same temperment.
Pine and gopher snakes might fit the bill too.

Eryx - All the fun of a boa in a convenient pocket size!

I have a jungle carpet and she is a great pet snake. When i first bought her I put her in a 20 gallon long. Then a 40 gallon breeder. Now she is in an 80 gallon tank.
JCP's are arboreal snakes and love to climb aroud.They are a great display snake, at least mine is. Mine was restless in the 40 gallon so I bought her a bigger tank. She is 5 foot right now. I've read the biggest ones can get to 8 foot. So a jungle carpet won't fare well in a 40 gallon. I love the colors of mine though. That is one reason I wanted a jungle carpet. Also I was looking for a snake that was big but not BIG. Even though they get to 6-8 foot they are slender so don't take up as much room as a boa.
The Iranian (sp?) carpets are suppose to be the smallest of the carpets...getting like 4-5 foot so they might be better off in the 40 gallon tank.
I also want to point out that the JCP are more restless and don't like to just 'hang out' on your sholder. Mine does great but is always looking for something to crawl on too. Some carpets are nippy as babies but mine is very docile with handling. She switched to rats with no problems but some will absolutely not switch to rats.
What ever you choose do your homework well in advance before buying...you will be much more happier in the long run. I also saw a couple JCP before buying mine so don't pick the first one you see what ever you chose. :0) This is my JCP..Sorry the photo is so large. I don't know how to post it so it's smaller...

Check out the pine, bull and gopher snakes. Most are in the 4 to 7 foot range as adults. They are famous for eating well. They vary in temperament but most are easy to handle. They're North American colubrids, so their requirements will be more like your Cal king than would a boa or python.

Hey i dont want anymore colubrids

i want to try new species like boas or pythons

Whats wrong with the good old ball python? If you want more exotic species a BRB would be fine if you just keep the humidity up. I know you said no more cloubrids and you like bigger snakes but my favorite snakes are hognoses(next to chondros), they are just great, full of personality.
it's a different experience than owning any other snakes. I believe they are under-rated and should have cornsnake status. Help me out hog lovers.
