Tips for large chested pumpers?

My ladies never came in perky 🙃 it’s like they grew too quick for my body to handle it and even before having a baby, my breasts have always been… pendulous. I have next to no fullness at the base of my breast, it’s all down low and my nipples have only ever looked at the floor.

IMO, this made it tricky for my LO to latch (along with his lip tie) and hence - my EP journey began.

I was gifted a momcozy s12 at my baby shower that I’ve been able to get a pretty good output from - but never felt like it has completely emptied me and I’m wondering if it’s a bit of user error just purely because of my breast shape? Is there something I can do to make sure I’m getting milk out from ALL the ducts so I don’t end up with a clog or mastitis? 🙃
