Honestly I don't know much about those pumps, but my recommendations for hands-free is to get good fitting flanges and a pumping bra. I also have small boobs (and post-nursing tiny boobs) The pumping bra made the biggest difference for me and let me do all my work like normal. One like this should do the trick:

A note about fit- boob size has nothing to do with nipple size! I was a size C before pregnancy, and a D while breastfeeding, but I had trouble finding flanges that were small enough for my apparently tiny nipples!
I had a Medela, so I followed their directions on how to measure for size.

As for hands free pumping, a pumping bra is your best bet, but it didn’t work for me. I got the best production doing one breadt at a time, holding the flange in one hand and massaging with the other. It took a while to figure out all the different variables. Like my nipples point upward, so I had to sit hunched over to get the milk to flow down instead of back into the flange

Good luck!

I like my Spectra pump a lot. I have both the kindred bravely sublime hands free bra and the simple wishes bra and they are both good. The simple wishes one goes over your bra and the kindred bravely one you wear as a bra but it also clips down for nursing.

For flange fit, I recommend asking the LC in the hospital - bring your pump so they can see it work and they’ll tell you if it’s the right fit.

I just ordered a set of Pumpin Pals and I think I’m going to get a set of Freemies collection cups for pumping in the car.
