Yellows tend to be more aggressive than greens, but have the advantage of staying smaller.
In either case, I would NEVER think of one as 'tame' by any means. I've worked with several adults and young - up to 14 feet long. Nothing a single person should ever get in with. Team work will save your life sooner or later. Feeding is a good point. They go off feed during breeding season, so it's not shocking for them to go 5 or 6 months without eating... especially a wild caught animal. They need a lot of water and a good terrestrial hiding spot.
