Just a note from one limit guy to another...

I'd really avoid playing one table of one stake and one of another. The games don't really play the same (though at the lower levels they play similarly enough to fool you). I tried playing one table of 3/6 and one table of 5/10 for a while and I got eaten alive at the 5/10 tables. When I finally said, "fark this, I'm moving up and I'm not moving back down unless I bust", I made my profit.

There's always a learning curve. The first 5000 hands are always the worst. Other words of wisdom go here.
