what a post!! i think the maritimes is super nitto with all the twintippers..
ya dan,
you know your shit when it comes to sking, but not when it comes to bindings...heres the deal;
your binding is crucial as we all know....
your daul toe piece can be adjusted very easiely, they misalign every so often and should be check here and there.  you will need a lamanated piece of paper, you should be able to slid this under your toe and thats all.  your toe angle tension can be checked by simply putting yur boot in the binding on the carpet, have one guy hold the ski and the other crank as if you were falling, you want 80 lbs torque. you can tighten your toe.
your din should read according to your standard chart reading, those charts are not BS.  maybe go up 1 0r 2 if yur comfortable with that.  If your din should be set at 6.5 (according to the chart) you should have a binding with a din of 3-10 or 4-12.  the rule: your binding din range should allow for your setting to be in the middle.  this allows enough tension on the spring to release and 'bring you back' if you dont crash and it also doesnt strain the spring.  i would say you need to have someoe look at you toe, that is a fine binding yur riding for your weight.
but
i will never argue with buying good bindings..it is very smart to have titanium, carbon, for obvious reasons.
and WU, you ski with pros and know there din settings, your so hot
