The B Series Pros are the ones made entirely by Bazzer, including the finishing (the reinforcing on the tips, adding the endcaps) Initially, the finishing was handled y Rev but, Bazz took it over this year. I -think- Bazz is now doing all the finishing, including his nifty leading edge refinements on most, if not all of the Masterpiece kites now as well.
I had sent Bazzer an email but never got a reply....is he making any single line kites anymore???
