My little vacation is extended a bit. I am now holding off until I receive more of the R-Polymer. I am out now.
B&S has indicated that they will be ordering a 20kg sack. That is the Kuraray minimum order . So, if anyone is interested in giving it a try, Kuraray will send you a pound for free. But it looks like it will be availible from B&S. 20 kg is a bit too much to have laying around.
