Who makes the best bearings for an EB48? Coming from the 1/10 on-road touring car world alot of us use unsealed (open) steel bearings, ceramic/steel hybrids or some nutcases go full ceramic bearings which are ridiculously expensive. I imagine ceramics won't hold up very long because they are so hard and don't have much resistance to shock loads and impact. Who makes the best replacement bearings for in the dirt outside off road racing? Thanks!
