I think it's great to discuss the WI7 rating. By definition, I believe WI6+X IS WI7. As far as physical demanding ice, I have climbed TONS of 5+ ice that was more physically demanding than a fair amount of WI6's. When u step up from 5+, I believe the grades reflect more danger rather than acrobatics. However, with that said, when you are forced to climb a 40 hanging, poorly adhered cicle because the rock to the left u were stemming on runs out of ANY feet, and u are only able to place one MARGINAL 10cm screw...roping out on a couple of the cicles I found myself 6-7 feet from the consistently overhanging rock...I'm not saying I'm the most credible on WI ratings, but Jess and I both believe that to b the craziest price of ice we've ever SEEN - anywhere, let alone climbed!   
  
DAMN IT!  Why won't someone just go repeat it already??   
(Note for potential second ascentionists; climb the bottom section, throw a bail biner on the #2 pecker, then lower off while cleaning the lower two fixed pins, pull the rope, then pound em in on lead). Lol. I would have cleaned the whole route on rappell, but I was 20 ft out from the wall due to the overhanging nature of the climb.  Plus we were in a hurry because it was a little warmer and didn't want the route to fall off and crush us like bugs.
