Looks like they dropped 1.7-2 lbs from the J107 Dragonfly or M series and a little bit of the cargo space 5425 in the dragon fly to 3100 in the elk hunter if I read that correctly.
But price is $299 for the elk vs $399 for the dragonfly.
Nice to see they are coming with options, but that scabbard sure is heavy. I love my dragonfly, but wish the scabbard was detachable to shave a 1lb or 2lbs.
