Spectra Pump Issue

I'm frustrated with my Spectra. I wanted to love it so bad, but it takes over 20 minutes to pump vs my medela, which gets the job done better in less than 10 minutes. I use/need my medela on full power but nothing on the spectra even compares for suction power. I end up using the let down mode for the whole session because it pulls out the milk the fastest for me. It seems like I've tried every cycle/suction combo. Any suggestions on a magical combo setting?
