Head Graphene 360+ Speed Mid Plus

The new(est) model of the very popular Graphene 360+ Speed series racquet is available NOW, so get up to “speed” by taking a look at the specifications for a strung racquet and the series comparison data.

The major difference between this and the previous version is the “flipping” of the colors! What was black is now white and what was white is now black! I believe not very much else was changed and for good reason! The racquet is a very, very good racquet so why make a bunch of changes? I don’t think Head made a bunch of changes!

Here is an overview of all the new Speed models. This is unstrung data, however, you can add 16 to the overall weight for string and 30 to the swing weight number to approximate the strung data.
