Binding din range

The 13 should be fine. When you're considering din, get the binding that has the din you want in the middle of the din range.

13 is fine, don't waste the money on the 16. You do not need it.

If you know that 10 is the correct DIN for you, and you know that you won't need a higher DIN at some point in the future, a 13-DIN binding is fine, but the 16s would be fine too, as 10 is pretty close to the middle of the range on both models. As Scotty Boy said, you should get something with the DIN near the middle.

If you are only concerned with DIN range and know you'll never need higher than 10, go ahead and get the 13s, but I believe the 16s are also more durable than the 13s. I'm not positive on that though, do some research.

When I bought my atomic sth2 13s I asked tompietrowski (who sells bindings and gear for a living) if there was a difference durability-wise between the 13 and 16, he said the only difference was the din range. Keep in mind that is the sth2 series, and not the sth series.
