By "serious" I don't mean to demean anyone who makes them as a hobby, I'm more looking to talk with folks that make them as a business.
If you don't use BCY, and are interested in some samples, I can help. Just call or e-mail if interested.

when i was in "the string business" i tried different brands of string fiber and by far BCY was/is the best, at least for me!
Has been for me also--best materials, best customer service. Their business has exploded since I got on board with them, but they haven't forgotten me even though my orders are a drop in a bucket compared to most of what they get.
