Therefore balance will move towards head heavy for about 1 cm(2-3 points) and swingweight will be increased by about 15 points.
Oh, so if I replace the original 630 grommets with the MG Prestige MP grommets then the racquet will be a bit lighter and a bit more head light. This is my first 630 and although I haven't played with it yet, it feels a bit heavier than my 280. So the weight savings will be welcome, albeit just somewhat lighter.
