Worrying about set over set situations is pretty counter productive. Those are just coolers. They are unavoidable situations where you're destined to get the money in bad.
If you're 6-tabling and only breaking even, one of the most common leaks in your game will be a falling red line, when you filter your results won without showdown. This is because you're unable to focus on each table as clearly and miss a lot of good bluffing opportunities, as well as generally cBet too frequently and then give up.
I know it's NL2, so there aren't that many opportunities to bluff, and ABC poker should get it done for you. But because you can't concentrate on each table as much, you'll find your reads are off.
Try 4 tabling for a little while and setting up the tables so there is no overlap. Use the bare minimum of stats in your HUD and focus more on the players at your tables.
Hopefully that will help your all import profits line start to rise.
