+1 What Mark said. I only have access to a 2.0 so I made sure to learn all my tricks on the long line too (I find it easier because you can cut harder and get the handle in closer) which will help you take it to a full size cable.
+2 ... the system 2.0 is a great way to learn air tricks. A short line will help a ton in learning them, it will be much easier to get extra help when loading the line.
