i wouldn't go anywhere closer to center than -3, i agree with the guy above.  I will probably be mounting my 185 JJs at -3, you don't wanna go center on JJs, these skis were built to charge the bc, and they know that in this day and age people charge switch and throw stupid shit off cliffs. the swing weight is like no other, and you will be able to ski switch, butter, and throw shit even back 3 from center
