Should I avoid rims that don't have eyelets? Does it really make a big difference in their longevity? I'm looking at these Fiammes:

I think they'd be perfect for my Carlton, but the lack of eyelets worries me. I've never owned rims without eyelets. I know they're necessary when using alloy nipples, but I'll be using brass.
