Thanks guys! So helpful

Another question... I'm a girl and I'm 5'3", will I have problems handling an adult rtb?
& when you guys say "in your face" do you mean they just want to get close to your face, but not aggressive? "Cuddly"?
& hook training... tell me about it. Do you just get him out with the hook every time you want to hold him? and keep the hook out of sight during feeding time? Or is there more to it?

So, in a nutshell, is this right?
- Once they're adults, a jumbo every other week to once a month?
- Ambient of mid to high 70's, hot spot of 90, and humidity at 50-60, and 70 in shed
- Usually stay under 10 feet, and up to 30 pounds

I have a 20 gallon terrarium with sliding glass doors and a screen top that I have completely decorated with a backdrop, fake plants glued to the wood background, driftwood, etc... I had originally made it for my 1st ball, but he's in a tub so I don't need it anymore, and he's never even been in the tank. Will that 20g be okay for the first year we have the rtb? We plan on building a full sized cage once she needs it.

The biggest thing we were worried about was feeding costs and adult size, but seeing as they eat much less than balls, that makes me feel better.

I have seen pictures on google that they look really big, both long and thick (that's what she said ). Are all adult rtb's like this, or is this just due to feeding bigger meals like rabbits, or jumbo rats every week?
