I've had both. I had an original duplex and sold it when they released the bikini frame and bought one of those. The bikini frame was stolen and I thought I would try a Kuiu Icon pro (I had the bag that was either 5000 or 5500, can't remember which it is.) I thought it was going to be a nice set up until I had to pack out a mule deer I shot. It kept sagging and I couldn't keep it up high enough. I literally had to hike out bent over. Sold that when I got home and picked up another duplex frame off the classifieds and sold that last fall for the new frame. I have hauled out several critters each year on a duplex with loads up to 110 lbs with no issues. For reference I am 6'2" 200lbs and was using a tall icon pro frame and 26" Kifaru frame.
