Those clips see pretty neat. I google cue sheet clips and found this home made one it seems simple enough to make and should be pretty light.

I like my little map-cue sheet holder I got from Adventure cycling about 12 years ago for $10. It velcros to my handle bar, is waterproof and has performed well in the nearly 100,000 miles in all kinds of weather it's been.
It's still $10 at www.adventurecycling.org

A perfect fit for Adventure Cycling's national route maps. L&C map panels are smaller so they are not a perfect fit.

For new routes, I use simple turn-by-turn cue sheets taped to my stem. And I never get lost! (And if you believe that....)

Binder clip and zip tie, maybe not so fancy but works the same!
