Are they using graphene so they can make their racquets cheaper and the graphite walls thinner so their racquets will break faster? I can't tell you how many times I've seen people bring head racquets to me where they are collapsing from the outside in and torn racquets holes where grommets are ripping through the graphite frames.
What they need to do is beef up their head guards or make their frames with a deeper channel to protect the strings. Secondly use an extra sheet of graphite so your frames are more durable. The graphite walls of head racquets must be paper thin cause they break a lot from the outside in. Sure this happens when you string it wrong but how many other companies have this problem and I'm sure those racquets are all strung wrong too.
