In the end the Rockcentrics performed well. If I am carrying large hexes the Rockcentrics are my first choice. And in smaller, strangely shaped cracks the Rockcentrics definitely fit more easily than angular hexes. My complaint about the stiffness of the slings still stands. The trade-off with the smaller Rockcentrics versus wired hexes is strength, flexibility and weight at the cost of a couple inches of reach. But that is a trade-off that many climbers will be willing to make, especially if you want to supplement an existing rack or simply plan on using them in anchors.
Pros: curved sides make seating for placements more effective; lightweight; strong; inexpensive.
Cons: Dyneema slings are harder to place than wired hexes.

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
