Here's a thread that should answer some question on the Squire:
Regardless of the quality of the squire compared to other equivilant bindings on the market; I think you would be better suited to a higher din binding (I'm presuming you're a level III skier), maybe at your size 14 plus. In the 14 din range look at STH14, which now features a driver toe, and the FKS140 if your sticking mainly to in bounds stuff. In the 16 din range I would go STH16 over Jesters as I have had some troubles with the heel piece sliding back on the rail causing me to prerelease. I would like to be able to comment on the Tyrollia/Head/4FRNT/Liberty equivilants, however I have not spent considerable time on either, so I do not feel qualified to give and opinion in a thread like this.
