Hi
I would recommend that you test the hole first because the bigger you go the more chance you have of tearing the tissue.
The lobes are quite elastic but like everything they have limits and if you tear them it will require sewing back up.
I saw this happen on a colleague who skipped 2 gauges (no idea what possessed them to do that) anyhow they need 6 stitches to repair the tear.
That said you know your body best.
