Where these two actually differ

- We flag Aluminum corrosion and degradation, Bearing and seal contamination and Metallic particle shedding from wear on the KastKing and not on the Berkley.
- The Berkley is monofilament nylon fishing line where the KastKing is Aluminum body, stainless steel, metal gears, which is most of the difference in these two grades.
- These two are level, close enough that price and fit should decide it rather than our grade.
