ThanksI think you'll find that @si_c's view is a tiny minority one (but 'bravo' to his expertise). I assert that most people think pushing out the broken link with the chain tool they're carrying and fitting a quicklink is both easy and reliably quick, the chain remains the same length (so you can cycle home and get out the next day too), and trying to push the pin back through is fraught with difficulty and repeated quarter turns, both out and in. Finally, what evidence is there that a reused pin is "more reliable too" than a quicklink (eg the KMC one)?
Appreciated
