I have the Rossi Axial 2s and have been a big fan of their performance. They are a very good binding for the money considering that all metal ones are very expensive. These are about as good as you get with plastic bindings in my opinion. Of course, if cost is less of an issue, then you should go with the Pivots or the FKS because of their added durability and safety features. I personally do not have experience with Tyrolia binding but a friend of mine has them and they have worked quite well for him. Also, I do believe that the PX 12s are the same as the Axial 2s but don't quote me on that. Just just my 2 cents.
