With regard to the weights used by professional anglers, I haven't seen any paradigm shift.
From day one, the pro angler tended to use more weight than the recreational angler.
To begin with, pro anglers are pitted against the clock and finesse fishing eats the clock.
In addition, the majority of a bass’s life is spent “OFF-the-feed”, which plays right into the hands of a faster sink rate.
There’s no better example than KVD, who built his career on the effectiveness of the 'impulse strike'.
I will say this, 20 years ago (mid 90s), fluorocarbon rose to fame as the new 'leader' material
(I used it for saltwater leaders). Today however, a fluorocarbon main-line has become commonplace.
Fluorocarbon is 'twice' the diameter of braided polyethylene of the same breaking-test.
In spite of the overblown property that fluorocarbon line sinks, let me pose a question.
Which main-line do you believe would require a 'heavier sinker' to hold bottom during a brisk drift:
Fluoro or Braid?
