Who is really in the lead coming into Ruby?

As the parade of Teams file into Ruby in the next moments of the race, you got to wonder...who is really in the lead?  11 Teams stretching 30 miles long are bearing down on Ruby....but only 4 Teams...Buser, Neff, King and Waerner have taken their 8 hour rest....everyone else, including Dallas at mile 341, Mitch Seavey at mile 340, Burmiester at mile 339, Aliy at mile 334, Ulsom at mile 327, Royer at mile 324 and Kaiser at mile 320 have not taken their mandatory 8 hour rest. I would suspect many of these Teams will do their 8 hour mandatory in Ruby....but Buser (Bib 4), Neff (Bib 24), King (Bib 59) and Waerner (Bib 8) can go whenever they please.  Buser presently has about a 20 mile lead over the rest of them, leaving Ruby to be a key checkpoint to watch the strategies begin to unfold! Its clear even with the start differential, Buser is in the lead with King a close second, BUT THERE ARE A LOT more miles to go....strategy will be key in these next checkpoints!
