Replying to Din Help

Hey NS,
I'm in the market for new bindings and figure I should decide on what din I'm going to be riding at before I purchase a binding.
I'm 5'9" 150 lbs
Level 3 skier
Age: 18
Have been skiing for 14 years
I ride park/mtn on 176 skis with marker griffon bindings with DIN set at 8
I like this set up, but have a question for another set

I bought176 Moment Ghost Chants 139/124/139
I'll mount them center as recommeneded, but wondering what din I should ride at.
8 works for my other skis, but these will be for "east coast pow days" and my binding knowledge applies to skiing east coast groomers, not dropping cliffs and skiing in powder.

So NS, should I be riding at 8 on these, or maybe higher at 9 or 10

My choices for bindings are
Marker Griffons 13 (high din)
Marker Jesters 16
Fks/pivot 14
Sth2 13
Sth2 16
