Hey guys, me again stuck with spear nuker. My masteries are going to be 90light/90cold/90heuksal . I am level 45 atm, and im pure int. Now i want to go hybrid!

Can anyone tell me , what phy/mag balance should i get to be a good hybrid, still wanna level fast but a bit more efficient at surviving. I wanna be mainly int.
OR .... stay pure int ?
Thx alot !
