Help me choose from these 4 wheelsets?

I was looking at maybe Mavic Open Sport's, or perhaps Rigida Sputniks... Am I correct in saying Sputniks are pretty sturdy (though heavy)?

Sputniks weigh about half as much again as Open Sports, but they're touring-width rims - minimum 28C tyres. Very strong though, yes. If you're looking for a narrower box section rim the Rigida Chrina is not at all bad, still a bit heavier than an Open Sport but cheaper - £15.50 each from Parker.
