The White version of the Cobra ZL Encore Driver is a style icon (used by Ian Poulter) and sells for huge bucks!
It offers flight control technology via an easily adjusted shaft connection (open, neutral or closed).
The black version is absolutely identical - but everyone wants the Ian Poulter version - and nobody is buying the black version.

This means that retailers are getting stuck with the black version - and are selling it much cheaper - often at less than half price.

Buying Tip:
The clubs are identical - so buy a bargain black version!
