Mizuno say this is because this is a MP 'players' club and it is meant to refine rather than change a ball flight. In our tests the settings were very easy to use and the changes were noticeable even if they are quite subtle. You can also create any combination of spin and draw/fade to suit your game. Where the total of the two positions add up to 11 you get a neutral flight, but moving both weights to the inside will promote a draw and vice versa for a fade. Moving the weights to the furthest forward points at positions 1 and 10 reduces the spin on drives, whereas moving them to the back and centre at position 5 and 6 increases spin. The real difference with the MP-630 though is the Fast Track system that increases the number of weight positions from 6 on the MP-600 to 10 in a channel that is U-shaped on the sole of the club. However unlike most Mizuno drivers this one really goes thanks to the excellent Mitsubishi Rayon Fubuki shaft that, despite its colour scheme, is ideal for this driver. It has a smaller 445cc head than the standard MP-630 driver and the classic looks means it sits beautifully at address like most Mizuno drivers. The Mizuno MP-630 Fast Track driver builds on the first edition of the Fast Track system from the MP-600 driver.
