Most of the pro's on the xda developer forums strongly advise against using task killer apps like juicedefender etc, it messes around with the android OS, which manages running tasks in it's own way. And free ram is wasted ram.
Erm, Juice Defender is not a task killer... Just saying
But yeah I'm also against it as well, but also recommend the use of Watchdog. https://play.google.com/store/apps/details?id=com.zomut.watchdoglite
