Anyone have any insight on whether I should get a rear Paul Funky Monkey (or similar cable hanger) for my Work that will be running cantis. It does have the internal routing but being that I haven't installed and set up cantis on a brand new frame that I can think of and haven't really played with them in a while (beyond riding bikes with them) so I am unsure what I need. I got one for the front but am thinking I should probably get one for the rear to help things out a bit but maybe I am wrong?
