Different Bags?

I just blew a bag on my drive home tonight, like 10 minutes ago. It was an RS72 up front. This is the 3rd RS I'v blown. Last time I blew the 2 backs. I replaced those with conitechs. Now my question, Should I just replace the bag with another RS or can I have two different bags up front? Im REALLY not liking these slams right now but I really dont think 2 different bags up front will work. Any help is great.
