Kevlar will probably work OK but may not be as good as metal. Music wire 
makes a good strong and flexible support wire. At a music store you can buy 
the thinnest guitar string which is 0.008" in diameter for less than $2. It 
will easily support a 5 pound mass. Secure the ends by clamping between two 
washers with a screw.

Have fun,
Cap
