Use of Polypropylene for Intermediate sinking lures

I have found that a Deceiver Streamer type lure tied using combed out white polypropylene string has been very effective as the poly does not hold water and actually has nearly neutral buoyancy.. tie the lure on a size upto between 8 and about 4/0 and use it with a little lead from a wine bottle top wound on the hook.. works a treat..
