Useful - Petzl Dual Connect Adjust

You just gotta decide if it works with your set of gear. For sport climbing when you're not too worried about weight, this is the cadillac of personal anchors.

Pros: It's dynamic, effective, and simple to use. You're buying peace of mind.
Cons: Expensive or bulky (alternatives like a Purcell-Prussik or even a sling would work just as functionally)
