Replying to Need Shoptech's Help (DIN)

I took my skis to my shop and got them mounted, however i must have entered in some wrong information because the shop set my DIN too high. I need to know what i should set my DIN down to from the 8 position they both have currently.

Skis: 189 Hellbents with STH 14 Drivers

         185 Armada El Rey with Marker Griffons

As i said both are currently set at 8 and i dont want to pay the shop to adjust them.

My Information:

Age: 16
Height: 6' 1"
Weight: 150
Skier Type: III
BSL: 315 mm

My El Reys are for park while my Hellbents will be for pow, big mountain and cliffs. The Salomon chart said a 7 for my hellbents but i cant access the new marker chart.

Please help but only if you guys really know what you are talking about.
