At 130 a 12 din would usually be sufficient. There a quite a lot of 12 din bindings on the market. Don't be put off by the fact they are 12 din, bindings such as STH12 Driver (steer clear of the Oversize) are plenty burly. The Rossi Axial2 120 is another solid option, it features the same toe as the Pivot 140 but has a different Axial+ heel, see the review on
http://aslansskiblog.blogspot.com . If you're set on the Griffon see if you can find the 10-11 model as I think that contained some metal.
Hope this helps, Joey
