I know there have been many posts on this dicussion. But there are a few things I just can not understand. :confused2: First, here is what i do understand. Many people will use braided line for the following reasons. 1) One, it has a smaller diameter and strength per diamater ratio allowing one to put more line on the reel with increased strength. 2) People will use a leader so they only loose their terminal tackle and not the expensive braided line. 3) Having a leader allows for different presentations. 4) Leaders also allow for the main line to maintain it's strength by not having sinkers stoppers or anytime type of things to decrease it's strength or create a weak point in the main line. 5) I know there is more but just can not think of them right now. Here is what I can not understand. For example, people will use 80# power pro or other braided line with a 50# mono leader. Isn't this defeatiung the purpose of a smaller diameter line? Why use the lighter pound line if it is only going to create a weak point in the connection? Isn't the leader going to have the most tension, so why use the weaker line? Another example, people will use 50# braided with a 80# mono leader. Again, the diameter theory? Sorry I ust don't understand this set-up. Lastly, I can see the advantages with this set-up while it has proven to be effective. However, I some things such as the idea of a larger diameter leader and smaller diameter main line just seem self defeating to me. If light can be shed on a few of these questions that would be great. Thanks to everone.
