I'm a certified shop tech and according to your weight, height, age, and ability level; you're skier code is 'M', with a BSL length of 315 that puts your DINs at 7.00.
However DINs settings have so many different variables, but legally shop techs have to follow each given value to set the proper DIN setting. But judging upon your level of skiing and equipment 8 will suffice for you. You can manually crank your settings higher/lower with a simple phillips or flathead screwdriver. Depending on how much torque you want to pop out of your sticks, I wouldnt set them lower than 7.00, how high you want to crank, you're preference!
