I can change the default arrow head via \tikzset{>=Latex}. However, it is not a given that the combination of an arrow head and its reverse looks good, so I would like to also change <> to something custom.

I have, on a hunch, tried \tikzset{<>={Diamond[scale=1.2]}} but that doesn't seem like the right syntax. Is there a way to set a default arrow head for <> endings?

You can define the <> arrow tip via the .tip handler (cf. section 16.4.4 "Defining Shorthands", pgfmanual):

  \draw[dashed,->] (0,0) -- (5,0);
  \draw[-<>] (0,2) -- (5,2);

enter image description here


You should create a style with tikzset

        \draw[myarr] (0,0) -- (1,1);

    Right, but I'd like to use the intuitive <> syntax, i.e. I'd still like to write \draw[<>-<>] ....
