I have LaCrosse Burly 1200 gram. Used them for 2 seasons of hunting and 1 of fishing so far. They have kept my feet warm on the ice. During hunting I found some draw backs. The lack of ankle support and soft soles makes climbing ridges a bit sketchy. I also dropped the money for a boot dryer, one day of hiking and they're damp, setting them overnight in front of a heater wont dry them.
