The Cobra Speed Pro D driver manages to combine the forgiveness of the usual Cobra driver with the style and playability that better players like.
The D version of the Cobra Speed Pro driver has a slightly deeper face the the S version and is therefore more compact back to front which gives it a more aggressive appearance at address and may suit the better player.
Personal preference and your swing speed will dictate which one you prefer, but both are excellent clubs offering good distance, forgiveness and trajectory.
Definitely worth considering as this club can hold it's own against top of the range drivers from the more premium brands.
