Had a pair of the neon 2012s on the echo 24 some time back, built into a solid feeling wheel for a single wall defo wasn't a floppy kipper. Can't comment on their ability to hold a grind though, I used them smooth.
I'd own another pair if that helps, doubt they'd be suitable if you're a partucualy heavy rider
Also agree with the eylet mention above, every eyleted wheel I've built just 'felt' better
