If I was as smooth when talking to girls as this Grigri is when it's operated, you could call me Austin freakin' Powers. Speaking of powers, this Grigri has a few big ones; first, the ability to switch between lead and toprope modes, which changes the sensitivity of the device so that it grabs the rope faster than your climber could grab the hold he/she was reaching for (which is probably why the rope needed to be grabbed). Next go for sure bud. Also, the new catch for your index finger makes feeding quick slack easier and safer. Or, flip it upside down and use the same finger catch to practice your mono crimps! Never know when you might use one. This Grigri's got everything. Use it to to belay, use it as a bottle opener (don't ask me how), or just play frisbee with it! You know, toss the old 'gri with dad every once in a while.
Some things to know before you buy this Grigri: It is more sensitive than previous models, which can take a couple sessions to get used to. Also, the "anti panic" feature on the brake lever means that it effectively has two lowering modes, one more assisted than the other. Again, this takes some getting used to but once you do, it will work like a champ.
