Troxel for western or One K for English
I have an Ovation schooling helmet and I got it for really cheap and they are great quality! I would definetly try one out!!
Charles Owen or Samsheild
KEP Italia and Casco if you want a more affordable one
IRH are pretty nice for the price.
I personally love my GPA and samshield equally, but ONEK helmets are similar to smashed for a fraction of cost
