Currently eyeing up Sapim Lasers which look similar, had some on some wheels and they felt so fragile but there is definitely a weight saving to be had so am still tempted also.
I’ve used the Lasers in a couple of mtb wheels. Then I discovered that Sapim actually don’t recommend them for mtb use. But they’ve been fine tbh. It’s literally the same spoke as the CX-Ray, just with less forging so not as strong. I like ’em, they’re inexpensive and usually come with proper brass nipples too. I’m pretty light and not especially fussed about wheel stiffness though.
(I always say the same thing but it’s true, I got my 29er carbon wheels built with the newer DT Comp Race and they seem really good, it’s just that they’re bloody impossible to google for)
