I like the Smackdown, I use it, it is a very good line. However a large part of it's smaller diameter is due to it's lower breaking strength as compared to other lines with the same stated pound rating. The stated rating for smackdown is much closer to it's actual breaking strength as compared to other "superLines" As an example 10lb fireline(25.3) has the same breaking strength as 20 lb Smackdown (25.9) and both, (10lb fireline/20 smackdown) share a similar diameter. Whereas 10lb Smackdown has a breaking strength of 11lbs. Paulus Just Fishing
