I love the vivid air. Super plush and pedals better than a coil and its light. I wouldn't recommend it for guys over 200lbs though. A few guys I know over the 200lb mark have had trouble with them and have to put so much air that they couldnt get the feel right.
I'm about 215-220lb and I love it. I would recommend it for heavier guys personally. Well...I also ride with a pretty good amount of sag (about 33-36%).
