Dil and O2 off board ? on the same or different side ? waooou sounds great !!!
Until February you could always fill the scrubber with some sorb, and fill the dil sphere with some o2 and use it in front of the tv with your wife as a surface manager
well that's what I've done 4 years ago because I couldn't wait to do the course
Have fun
