The GriGri2: Another Step In The Right Direction

While there are some folks who prefer to avoid GriGris and see them as an insult to proper climbing technique, I commend Petzl on a revolutionary design that spans the climbing world from the greenest beginner to the most experienced athlete. The GriGri2 is just another step in the right direction, building upon a legend of design. While the specific changes from the GriGri do not warrant a mandatory upgrade now, the GriGri2 will probably replace it's predecessor over time and continue to meet the tallest of climbing demands.
Pros: Best belay device ever; lighter, smaller than the first GriGri; PDC; wider range of rope diameters = 8.9mm - 11mm (instead of the older prescribed rope sizes of 10mm-11mm).
Cons: Bites more on fatter ropes; not improved enough to buy the GriGri2 before your old GriGri wears out; where's the headphone jack?
