Any guides on how to determine flange shape?
After EPing with my first, I’m now wheeling the pump back out now I’ve had my second. I have been reading about different flange shapes (I’m not sure I recall this being a thing when I was pumping before?!) and I’m now thinking I may be better off with a saucer shaped flange. Does anyone know of any guides etc on fitting these please? Particularly in terms of flange size, they seem to be a lot smaller generally than the classic shaped flanges - are the nipple measurements done the same way for different shaped flanges?! I use 21mm inserts on the classic flang, but the saucer flanges only seem to go up to 15mm.
