You should check with the vender and get there imput. also check around to see what the fast guys are running?
With that in mind running different compounds front- rear is no issue ,your style and bike setup are as important as anything.
So try different compounds front / rear you my like a med front with a soft rear ?? I have also run a slick rear with a dot front with good results again bike setup will dictate what feels good. Track conditions are also a factor. So keep a open mind and good luck.
