What snake do you recommend as the next step up from beginner?

Hey I’m a somewhat intermediate snake keeper and I want to take the next step up to a larger python or maybe a boa I’ve had experience with a couple other snake species ball pythons and sand boas and really want something more substantial I want a larger snake I love my ball python and sand boa but I want to get something that’s a lot larger I know pythons like rock pythons and retics aren’t reccomended for people who are knew to keeping large snakes but i was wondering what any of you guys thought. I was looking into burms and Central American boas already and I want a snake species that can become as tame or close to as tame as a ball python just withought the whole potato feel that comes off them and I want something large but not massive I was thinking the 8 to 15 foot range also I want a species of snake that’s slightly forgiving with there care so if I accidentally screw up slightly like forget too must for like a day or have to leave on vacation they won’t die on me.
