Not trying to change your mind, but you get more balun for the money with 
multi-turn
toroids. Multi-turn toroids yield a choking impedance proportional to the 
square of the
number of turns. Turns are cheap. W2DU baluns yield a choking impedance 
proportional
to the number of beads. Beads are expensive. I have the very W2DU chokes 
that you
want to build and don't use them.
