Replying to A 110 brake on a 102 Ski?

So I purchased a pair of Backland 102's and went to my local reputable shop to get a binding. Ended up settling on a Griffon binding; however, they only had a 90 or a 110 brake. The tech visiually tested out the 110 as if the brake was upward if the boot was pressed in and advised it will work as it did not hang over as bad and stated I would literally have to be sideways in order for the brake to dig into crud etc. I do plan to maybe get onto a 109 or so width within the next couple of years. So I just wanted to ask you all what you think about this. My only other option was to bend out a 90 mm brake to make it fit, which I'm not the biggest fan of bending things to work. I just want to make sure everyone agrees with this. They will not even get to my skis until late Friday so I have time to back out if need be.

Thanks in advance everyone.
