What size flange do you use

Brie

What do you use? Is it actually the correct size.

I measured my nipples and they are 14/15mm. I'm currently using 20mm flanges and I don't know if it's worth buying new ones.

I have no pain and great production. I notice sometimes my nipple will get stuck on the side of the flange and my output isn't as great until I get it more centered.
