Which VCDS cable do I need to order?

I went to the ross-tech site to see what cable I need to order to do some tweaks to my new car. I'm wondering if I need the KII-USB, Micro-CAN, or HEX-USB+CAN? I don't have any other cars this will work with.

You need one of the "CAN" labeled cables - unless you also wish to help others who have older (Mk4) VW family cars... (meaning: the Micro-CAN is sufficient... the Hex+CAN would have the ability to also scan older cars...)
