Replying to Salomon guardian 13 or 16?

Hi NS!

I'm buying my first backcountry setup and got stumbled around the problem of picking bindings.
Salomon Guardian/Atomic Tracker seemed like an obvious choice since I mostly shred in park and want to transfer my magic skills to the backcountry land, send quadruples, future spins and ton of gucci stuff!

Since from now on, this text will be related primarily to the same binding owners or tech gurus, I will quickly ask my question.

I am 178 cm/ 5.8 feet tall
78 kg/ 172 pounds fat
and advanced ski guy.

What will be the best choice of DIN 13 or 16 on these bindings?

Currently I ski on markers with DIN 10 and feel like 13-14 will be more than enough, but still quite confused what to buy. So, what do you guys think? Bigger is better?

Thanks!
