Replying to Al Dentes W Marker Bindings, What size

I recently purchased a pair of Al Dentes and I'm looking at a pair of 2015 Marker Griffin bindings. The waist width of the Al Dentes is 96mm, but marker griffin bindings come in 110mm, and 90mm on Evo. I don't know which size I should go for. I live in Virginia, and most places you go to get your skis mounted they aren't very experienced. So if i get the 90 mm bindings idk if they are going to bend the bindings to fit. I'm worried that 110 is too much for 96 mm.
