As far as the gurgling goes are you using the short nut provided with your Ithaka? I never had with my high vg mixes and bf open to both channels. I have not tried and high pg mixes. You can try the the longer nut in the ceramic cup and check the gurgling action.I turned basic feeding on today to see what it was like. i get a gurgling sound and a more airy draw. while i like the convenience of having it open, i dont think ill continue to use it this way unless i am using heavy VG juice. the hit is less consistent it seems.
anyone else have a similar experience?
