In reply to LJC:
It's not so much the pack size, but the fact that if only one pole is in it's long 'setting' then it is more prone to damage than if they're all the same length.
Do you not find it annoying when you pull a pole section apart and the ferrule comes out of both sections? Or one section completely and partly out of another section, leading to an increased risk of crack the end of the pole section? It's not happened to me, but from a year's experience of fixing broken tent poles it wouldn't surprise me.
Either way, glad it doesn't both you. Do you know why it's like that though?
