Thanks, that's really helpful. It's easy to get caught up in all the (very expensive) hype.
It's not exactly hype. The difference going from a v1 Pocket Rocket to a Power Pack or a Pocket Rocket v2 is ease of use and for me at least it really really mattered.
The Pocket Rocket v1 flew well, depowered well and went upwind well.
Where it lacked was the ease of pack down and redeploy, the comfort of the lines when stowing, how easily it might back stall if you got hand placement off, the annoyance of having lines connecting to the middle of the bar (not a clean bar), the lack of steering due to long and slack lines, the amount of times it tied itself in knots and how much time you spent managing those issues in a session.
The hype isn't really that much about performance when you are just riding - it's about how easy it is now getting to access that performance over the earlier versions and how little time is now spent managing lots of little problems rather than just enjoying it.
