I just use Activator for my swiping gestures. On the homescreen, I have swipe up from bottom left, center, and right to open up multitasking bar.
When I'm in an application, I only have swipe up from the left and right side of the bottom of the screen to bring up multitasking bar. Swiping up from the bottom center of the screen in an application, closes the app (similutes press of home button).
Been really happy with these settings so far.
