I've voted for 1, but would be happy with 2 as well. I don't mind black, but would prefer a lighter colour if possible... (I'm not sure the black-being-hotter is true, BTW, I think I've read that actually its more to do with the level of ventilation in clothing terms. Muslim ladies seem to survive without heatstroke, in the Middle East...)
I don't know if we have any Muslim ladies, but imagine the Cyclechat burkha...
I reckon if 50 is the tipping point for cheaper, it's worth trying to go for that - although I can't afford (and don't need) more than one. I know it means someone making a speculative investment, but is it worth going for 50 anyway, and having them 'in stock' for future interest?
oh, someone mentioned the cardboard thing it comes on, and discarding that for postage - as I remember it, that cardboard has diagrams of different ways to wear it - is that right? Maybe it could be a postage option, if someone is prepared to do the sorting out...
