Try easeQuintOut or easeCircOut for the initial tween. Also maybe set the pause so it's 50ms less than the initial tween duration so that you overwrite the tween before it comes to a full stop. I believe bounceOut starts with the regular linear easing, but the delay you add for the transition is what will be causing it to move slower.ok, try this...
Set the first tween so that it covers 50% of the distance with half the delay you set for 100% then have the bounce out start immediately after with the same delay value. The amount of bounce should still be less than before. I'm sure if you mess around a bit that you will get it right.
