Compiling a "wish list" for baby #2. For LO1, my PISA was a workhorse and kept him fully fed for 2-4 pumps a day, for 9 months. I have four questions, please answer whatever you can:

1) Can Medela Freestyles be hacked to work with Freemies?
2) If I used the PISA at mostly full suction for most of the time, will Freemies give me enough section to mostly or fully empty?
3) I was also interested in the Spectra due to rave reviews, but the PISA's suction worked for me and it seems that the posts have said Spectra is not as strong? What about freemie capabilites with that one?
4) LO fed from Lasinoh (wide neck) bottles, so having two sets of bottles as annoying. Should I consider the Lasinoh pump? What about suction and freemie capabilites with that one?
