Help with nike vapor 4 studs?

Question

Hello, i am probably ganna buy the new nike mercurial vapors 4 but for use in rugby i was just wondering if the firm ground or soft ground studs are legal and if not is there a way of getting replacement studs that are legal. Its just so it saves me the embarresment of turning up for a school match a few weeks ago and the ref told me to change them and i had to wear a pair of S****y ones from lost property and miss half the game.

Answer 1

in rugby u can have anything but metal blades

Answer 2

as long as your sprigs are shorter than 18mm you should be fine, the blanket rule here (NZ) is 21mm but some grades use different lengths.  The 18mm stud is the shortest maximum length in use.  It sucks because I have 24mm, which i love as a prop, but when I went to play in Canada, they wouldnt let me on the field.  

By 4 Stud, do you mean 4 at the front with 2 at the back? I've never seen 4 stud before... I wear 9 stud, but again, prop.
