The Petzl GriGri has long dominated the auto-locking belay device field. The Trango Cinch now challenges that. The main advantages of the Cinch:
- Price: $25 less than the GriGri
- Ease of paying out the rope with a brake hand still on
- Weight: 20 percent lighter than GriGri
- Recommended rope size range. Trango says you can use 9.4-11mm with the Cinch and Petzl only recommends 10mm-11mm with the GriGri.
