My comments were not meant to be contrary to yours. You know better than most people in our intrustry the importance of dimensional accuracy in the conductor, insulation and jacket, given the cost of raw material contribute up to 80% of the cost of the conductor/cable.
KSM has proven time and time again that investing in an, as you put it, very expensive piece of equipment invariably results in enormous savings in production costs. We have seen ROI's in less than 2.5 months.
In my, possibly biased opinion, no cable campany should be without a KSM.
