There was a bass show on not to long ago and the went to I think was the berkley plant, it kinda looks like a hightec bakery, they have high temp mixers and then shoot the results through very small hole and the line cools very fast, then there is a set of lights that the line is run across that I think harden's the line and measures it for blemishments, It was a cool show, I bet if you call or email them the have vidios that they send out....DJ
