James is now working with Craig Boynton (Isner's coach), who spoke with us at the GSS Symposium. I asked about Blake's gear, and he explained that the issue was the specific graphite composite used in Blake's Dunlops came from the airplane industry. Apparently, Donnay was able to track some of the material down in an airport in China. Then, they made Blake's new frames from the aquired material.
