Yeah, it's tough to know what will work.
I guess I figure that once you are down a break and everyone has served once, you have to change something. Aussie or planned poaches can work but it depends on your partner's familiarity with these things.
Everyone knows how to play two back, so it makes for a nice option.
I have had opponents play two back against me, and it does mess with my head. I find myself wanting to *make them pay*, so it is tempting to try new things.
