I've only done 2000 miles or so on my Dahon Mu SL, but it's issue free apart from the little plastic sleeve on the head tube that used to accept the knob on the stem to keep it folded. That sleeve broke open, causing the bars to rattle around a bit when folded. Both hinges look really good still and no creaking anywhere on mine. I think the curve will be very similar frame wise so the hinges should be as good as mine.
