If I'm using the test probes on points where they can't grab very well, the slightest movement can make them pop off. It would help if you offered more flexible, smaller gauge, wires. I can appreciate the compromise between making them flexible and making them last, but I'm sure you could find something better. Also, it would be good if we could leave off the ground wires we don't need. How about allowing each wire to unplug separately from the connector, or just giving us a kit so we can build our own?
