I've been riding Bronson Raws since late summer and plenty of dusty as fuck indoor sessions and they're going strong. Fast, loud, consistent. I'm sure they're China made junk and maybe I just got lucky with my set, but I've had to constantly mess with many different pairs of Swiss from them seizing up fairly quick. 6 balls and regular 7 balls. So idk, try some Raw's if you want. I dig em.
