front sway bar suggestions

thanks guys, I will go with the Hellwig 1 1/8 on the front. he has some sub frame connectors already he hasn't put on yet. If I like it I may put some on my Duster. With that 440 up there it gets a little dicey on some of the back road curves around here. I was just curious because the book said you need to go with front and rear and they needed to be matched. I thought that was not completely necessary.Thanks
