i can almost be positive that we don't have this tool. I personally wouldn't mind having the mavic spoke wrench as well.
I think the Unior Spoke wrench is generally regarded as the best (new) spoke wrench on the market at a reasonable price. Nice wide flat area for your fingers and thumbs to get plenty of leverage without getting sore. Also grabs four sides instead of three (unlike the Park tool, the gap is in the corner instead of the side to increase the grip area).
