One other thought regarding flexible wire and the RDS8000:

If flexible wire is so readily available, why did Sanwa use a wire that wasn't up to the job ? I'm sure they didn't mean to make such a mistake. They probably used wire from a different vendor, or their existing vendor changed specs, or they just took a chance on a cheaper wire and assumed it would do the job. Or maybe their vendor made the wire incorrectly and didn't know it until there were thousands of units sold. Everybody makes judgements like this in the competitive world. If a manufacturer uses only the "best of the best" throughout in a design, the final product will too expensive and won't sell in the competitive marketplace.
