I live with the added stiffness because IME the tonal compromise of the Melody is not worth its added flexibility...you give up too much of the Lyric's goodness to gain the better handling...I'm wireless most of the time but what I love about the EA Lyric HG is when used live it can bang around on the floor or stage with no noise at all. It is very stiff though. A great compromise is the EA Melody. (The blue one).
Have not tried the Klotz so I can only give you the EA report
