Leader Building

[Long Island Guy]

There are a few other posts about this in various locations and mixed into other topics. I've used the "search" feature on the forums as well, and I have noticed that the specific sizes of things like Barrel swivels and so forth are missing, and as a noob to this subject I'm rather left in the dark! I'm looking to save some money, and to learn all the knots.

I have two questions regarding leaders. I use fluorocarbon 50# 3 foot section of leader at night with eels. This is attached to 30# fireline on one end via a spro barrel swivel 130# test and on the other is attached to a 6/0 Gamikatsu Octopus hook. Is this too heavy of a setup? I chose it because of the rocky conditions and rough structure and felt that I could more easily get away with the 50# fluoro at night. (setup also used in the Cape)

The other question is in regards to lures. I am not sure what strength fluoro to use, what size BB swivels, and if i should use a snap or tie directly as I have seen a # of different responses in regards to this topic. If you guys could respond to this question in terms of a light tackle setup (small tsunami/storm shads/jigs) versus a heavier one, (using lures 2 oz or greater) I would appreciate it. Remember I'm using 30# fireline for the heavy stuff and 20# mono for the light tackle early spring approach for schoolies. Some responses that I have received from other people include using the same test fluoro as the fireline and mono, because of the low visibility of the fluoro, it provides something to grab when using the braid, and is more abrasive resistant. Others have said to use something 10-20 #'s higher then the original line. Thanks in advance.
