i'll do ya a favor, and give you the direct link
to a nice, to-the-point article in urbanvelo.org about
your new, favorite sport.
the magazine itself is pretty cool.
mess with your browser from the above link,
or go to the urbanvelo.org site directly.
it's pretty unwieldly; try the pdf form, i suppose,
or go to the table of contents, and alter the address yourself.
but there are instructions how to build your own mallet.
