What din setting do you currently use? Someone your size could use a 12,14 or 16 din binding but we need a bit more info to advise anything. How aggressive do you ski? Where do you ski? What were your old bindings? Did you have pre-release issues?
If you do go the STH way, just bear in mind that the only difference between the 12 and the 14 is the DIN range. So if you're skiing on 9 now, you'd only need to go 14, if you think you setting is going to get higher.
