what chain and how many links

[rap169]

Ok im gettin all my parts together for my winter build. What chain does everyone reccomend? I was thinking abot goin with the X-ring, but is it worth the extra? Is a o-ring just as good? Also, what brand. RK, DID, Renthal And how many links do i need for stock gearing?
thanks in advance

dont buy an xring...they are waste of money...get any oring chain, im not positive on the links but heres a bump
