[amsat-bb] so67 - tone or no tone?

Now that we have a week of so67 activity I am confused about the tone.  I am currently using the tone, and made 1 contact (new grid!) on the only pass I could work yesterday.  I'm also reading a few reports about not using the tone as the preferred method of working so67.  What is the BB vote - tone or no tone....or doesn't matter?
