Hi Craig,
I’m fine thanks a lot for asking. I hope you are doing fine as well.
My suggestion would be to cache (MoGraph cache tag, Dyn-Chache should work as well, but with out a scene file, I would go with the MG cache as suggestion)
This allows you to move the time-slider back and fore. If you found the right position (as you mentioned already) you select the cloner object, and press the C Key. then delete anything you don’t need.
I would save the scene always before you do that, just in case.
If I get a scene-file from you, I will be more detailed perhaps in my answer.
Have a good one
Sassi
