i changed my binding to CAD 09-10. I'm so amazed with this bindings. They're metal, solid and stiff. Also you can tune them more(ankle strap, base length, custom balance bed, etc..).As i was told, they're stiffer then Double Agent, and they're as close to the hardboot bindings as you can get. They cost more then DA in the season BTW(330 vs 260 bucks). As you're alrady told,they're quite heavy, but it's not a problem as you don't get in park.
What board do you have? You got to have a nice one to put CAD's on.
if you say, CAD is cheaper then Targas, get the CAD.
