If you are going to NF early in the season you won't need much insulation. You will likely do some serious hiking, so LIGHT Weight might become your first priority. Take extra socks to help deal with moisture. Unless your outfitter is going to put you on stand, heavily insulated boots are not desirable.
Personally, I like the 400 gram insulation for hunts that keep you on the move. You will not need even that in September.
My preference is for the Lacrosse boots.
