Stealth bearings come in three sizes 2.0mm (shader/colour) 1.5mm (all rounder) 1.0mm (liner) Most folks go for the 2.0mm and use it for everything I did try the 1.0mm but it tended to snag the skin a great deal. the 1.5mm works OK and you can do everything with it. The stealth is Ok to dip your toes in the rotary ocean but there are far better machines out there for not a great deal more money.
