OK, I buy that. I thought by the way you said it was that the repair could not be done without a spare pin in your bag. As you say, chains break infrequently enough that carrying spares for that eventuality is pretty pointless. My feeling on this is, when it happens, repair the chain using a chain tool, finish your ride, go home and then replace the chain, hence removing any long term issues you might have with a poorly repaired HG chain!
EDIT: I have to laugh at the idea of carrying latex gloves with you at all times!
