You can specify an ease for the yoyo (backwards) portion of a repeating TweenMax animation. Set it to a specific ease like yoyoEase:Power2.easeOut or to flip the existing ease, use the shortcut yoyoEase:true.

TweenMax is smart enough to automatically set yoyo:true if you define a yoyoEase, so there's less code for you to write. Score!

Code

//this tween has a different ease in each direction
TweenMax.to(".green", 2, {x:700, ease:Bounce.easeOut, yoyoEase:Power2.easeOut,  repeat:10, repeatDelay:0.1});

//setting yoyoEase:true flips the bounce so that you have a Bounce.easeOut in both directions
TweenMax.to(".orange", 2, {x:700, ease:Bounce.easeOut, yoyoEase:true,  repeat:10, repeatDelay:0.1});
