The EXP1 started as an experiment — that's where its name comes from. Better players wanted even more speed and more fade than the Polaris LF (discontinued), and the EXP1 was the answer. Once again, it was an immediate success, and it has become an important part of the Millennium line. It is our best driver into a strong headwind, and it is great for linedrive shots. If you can handle it, the EXP1 could be the answer for you.
