well for me all my kbs is cast iron.
yup my supply do supply pro grade ones..
but due to my budget I never buy instead buy the cast iron ones.
I do asked before whats the differece between pro grades one and cast iron.
if I remember one member here mention pro grade one the shape is all the same.
be it 16 or 24 ..whereas difference on cast iron is their shape is different as the weight go higher,,,which I mean from small to big in the shape.
correct me if I am wrong here.
