I have never really understood what the gear ratio or the number of berring really mean. I know that there is a difference in what is needed for different game fish but what is the best for catfish? What is the best for certain sizes of fish? lets say from 1-30# and 30-50# and 50#-ect. I would also like to know what all the ratios and berring #'s mean. I am sure there are other fishermen out there who wonder what the numbers mean. Hope some of the replys will help. THANKX!
