Replying to Dynafit pin bindings and using at the resorts

So this season I bought a touring setup and put a pair of Dynafit ST 12 rotations with the idea in case of another shut down from covid, I could lap the resort.

Turns out I really like touring. I've been using my touring setup for almost every day I've been riding which consists a skin lap in morning at the resort and riding for a few hours, and the few full days of powder skiing we had. Pretty much a lot of resort skins/skiing due to a shitty snowpack and lack of ski partners.

Fast forward to a couple days ago when I was having some boot work done, talking to the bootfitter he warned me about skiing hard icy conditions with my pin bindings. I mentioned I was rocking Dyna ST 12 Rotations which I thought was the one of the best options for touring/resort pin binding I could get.
But he said to still take caution as it was his preference (he made that clear as he pointed out he is in lighter pin setup) that he will always switch out of any pin to a regular binding when at the resort on shitty/subpar conditions.

I'm still fairly new and learning about pin bindings so my question is this just one skiers fear from a light weight pin binding or should I be concerned and check my gap?

And while we are on the subject of checking gear, what pin bindings do you have? What maintenance do you do or problems you check for?

Thanks for any responses.
