Competition Mode and Launch Control

[alien]

Just wondering how people are finding these new features in the E2 Series HSV's.

For those that are unfamiliar, visit the HSV website, or see a quick video here: YouTube - HSV E Series 2 Launch Control Garth Tander

Everyone has complained about how "Power" mode doesn't really help for take off's, well this is your solution

So thoughts on it? Or if you own an E2, how are you finding these features?
