Sorry to make an ongoing joke, that was not my intent. I have a really high opinion of Eddie's comments, I've gone through his site extensively and my opinion is that this guy thinks outside the box better in this hobby than anyone. If he says there is "parasite draw" and it's not an official term, my bet is that it's there, I just don' t know what it is. My Isobar is about three weeks from being ready and I was just hoping to get a better understanding of this term.
