Just like old toeclips, it's going to be the one on the bottom of the pedal that will necessitate flipping the pedal.
The heavy side on a combo pedal (at least mine) is the edge of the pedal that has the spring loaded mechanism:
The pictures are a little disorienting since the bikes themselves are hanging vertically from my garage ceiling by their rear wheels. The silver bike is one I'm building up for winter and has A530 pedals on it. The blue bike is my road bike. It has single sided pedals which also hang mostly vertical (but tipped back a bit).
I have no idea which combo pedals you've tried, but these actually work pretty well. It also took a break-in period for them to consistently hang like this.
