The Park tool you mentioned - is that the
CWP-7?
That's it. If the Nashbar tool is like the Park, use the larger end for your system. Thread it into the crank as far as possible before turning the nut to remove the arm. Works great. Also, see Sheldon Brown if you want to learn more than you'll ever want to know about it.
