Go for the boss node first. I got Yuu-chan and Sakawa there, and only then I switched to farming K node. K node is much more economic - for me it's about 10x cheaper in resources, so even if drop rate for Roma is 3x less, it's still better (if more tedious) in the long run. And, of course, you might get Roma in boss node first :) For safety set up a margin - say, 20k fuel or so, and if you don't get result by then, switch to K node and gather resources for a bit. Eventually, you'll get them.
