Particular Logo Explode then Suck Back in to Form Logo Again

Hi all.

I am creating a design in which I blow up a logo ( the letter F ) and it explodes in slo-mo. Then I am going to have it suck back in to form the F again. I have it perfectly exploding from the F and then sucking back in using Z Wind. The problem is that when it sucks back in it doesn't go back to the shape of the F and just goes into a oval shape. Any idea on how to achieve this without using 2 diffrent emitters?

I am using Layer as the emitter type and an AI file as the letter F.


Thank you.
