[Increase and decrease fontSize using tween]

Thanks for the clarification, can you suggest what is best ease: should we need to use in this case I am little confuse about that.
 

[Increase and decrease fontSize using tween]

I am playing with spiral animation using tweenlinemax, I saw couple of examples related to spiral animation for growing text font size during animate but I also want to reduce the size of font after 1 second duration.

 

tl.to("#Text",10,{attr:{startOffset:'100%'}}) 
  .to("#theText", 5, {fontSize:50},2)
  .to("#theText", 5, {fontSize:10},1); //this is not working

so is there any way to grow up and down the font size while animate on SVG path using tweens.
