The ultra doesnt burn nearly like the old Blazer....or Cobra....does.  Seems to do the job on the pigweed though.   I'm using a pint.   I think the current prices say use Cobra instead of Blazer if you have to go over 1 pt.  The Cobra controls more species then Blazer does, I think I could get by without a kicker with Cobra on a lot of acres. 

I've got fairly cheap Storm on the way, so I'm set for this year.
