Packing Supair Acro 4

Hello eveyone

Im brand new on this Forum
I just started on my journey in Acro
Currently i fly with a normal harness and an additional resevere in a frontcontainer but i dont really like the frontcontainer
currently im looking at the Supair Acro 4 but because i mostly use my motorcycle to go flying packing is a bit of a concern for me.
Does anyone have some experience packing that harness?
If yes, what size pack do you use?
