CNO MKIII (Troels Gravesen) experiences?

I am slowly falling in love with Troels' CNO MKIII design; i've been wanting to try the T29CF002 and W18NX001 drivers, and the crossover seems beautiful in all its simplicity, even though the component values aren't unveiled.

But.. I am struggling to find any reviews of the MKIII version.

Has anyone built it or heard it?
