Hands free pumps-bigger nipples

What brand do you use? I’ve seen people recommend Freemie, Elvie and Willow. The problem is they only go to 27mm or 28mm flanges. I use a 30 on my Medela pump currently. A 28 /might/ be fine but I found the 30 more comfortable. I don’t want to spend money if it won’t fit and will hurt but it’s also Black Friday so there’s some deals. Any help?
