Yeah, can’t go wrong w those, or Odyssey, etc... ODI makes lots of these for various companies, but basically any legit BMX grip like these https://www.danscomp.com/bmx/Parts/Grips/

is gonna be better than most other flat bar grips if you want a thicker grip that isn’t slippery. (Kind of important in BMX, after all). And plenty of flangeless options.
