Spectra recommendation for flat nipples

Hello mums, I'm a second time mum and would like your help in chosing a good breastpump.

I have flat nipples and they hurt a lot everytime I pump. I use the bellababy electric pump and youha wearables. I have been measured n I'm using the right Size inserts.

I remember using the medela symphony pump at my LC's clinic and my nipples didn't hurt at all. It had such smooth yet strong suction 😍

Can you pls recommend such pump for flat nipples? I would prefer spectra as I saw a lot of moms recommend it. Which model in the spectra would you recommend if I've to pump at work as well?

Thanks in advance ❤️
