[Tex/LaTex] How to style Tikz arrow tip for state-loop

Question

I want to have a state-node with a loop, where the arrow tip is customized (here with -triangle 60). How do change the arrow tip a loop uses?

Heres a short example. I expect the loop to have the same arrow tip as the edge from start to end.

\documentclass[a4paper,abstracton,11pt]{scrreprt}
\usepackage{tikz}
\usetikzlibrary{automata}
\usetikzlibrary{arrows}
\begin{document}
\begin{tikzpicture}
\node (loop-node) at (0,0) {node};
\node (path-start) at (2,0) {start};
\node (path-end) at (2,2) {goal};
\path
(path-start) edge [-triangle 60] node {path} (path-end)
(loop-node) edge [loop above, -triangle 60] node {edge} ();
\end{tikzpicture}
\end{document}

Now I would like to understand why its not working as I expect, and how I can change the arrow tip for loops.

I also tried to change the style of the loop with
loop/.append style{-triangle 60},
with and without \tikzset, but that seemed to be a dead end.

I have no idea why your example doesn't work, but specifying the arrow tip with ->, >=triangle 60 instead works for me.

\documentclass[a4paper,abstracton,11pt]{scrreprt}
\usepackage{tikz}
\usetikzlibrary{automata}
\usetikzlibrary{arrows}
\begin{document}
\begin{tikzpicture}
\node (loop-node) at (0,0) {node};
\node (path-start) at (2,0) {start};
\node (path-end) at (2,2) {goal};
\path (path-start) edge [-triangle 60] node {path} (path-end)
(loop-node) edge [loop above,->, >=triangle 60] node {edge} ();
\end{tikzpicture}
\end{document}
