+2 Hillrider - get them all. You'll never know when they'll come in handy. Keep in mind that special propritary spoke nipple sizes are becoming more common. Shimano and Mavic come to mind. I am surprised to not see Calvin mention this considering two of Park's new tools this year are the wrenches to handle Shimano and Mavic.
1 year too late...I had to make my own for Shimano
