I'm new here, I'm sorry if the question has been up before.

You may also excuse my very bad english.
I'm wondering how far you generally can go when stretching a helix piercing before it gets deformed?

I have reached a modest 8ga/3.2mm. How big do you think I'll be able to go before I have to get i dermal punched?
Sorry I couldn't post a picture with my own ear... Those pictures are in a other computer's hard disk.

Thank's!
