This is the Mantis Power 110 squash racket.

This photo is from the 2013 Tournament of Champions in New York City. I managed to catch a few minutes of it in person last Sunday, and got to see Coppinger upset Adrian Grant and make it to the quarterfinals, a good result for him.
Anyway it looks like you can pick up the Mantis in the UK:
