Lots of different stuff out there but these are the ones I use (all lines in bright green colors unless described otherwise):
Sufix Tritanium Plus in 17# (.40 mm) - nice soft line, good casting, plenty strong enough for drum...I probably won't buy another spool as I'm going to Pro Spec
Sufix Tritanium Plus in 14# (.35 mm) - use this on my bait rods
Berkley Pro Spec in 16# (.37 mm) - good, tough line...16# for stripers
Berkley Pro Spec in 20# (.40 mm) - this is the line on my drum sticks
Berkley Trilene Big Game in 15# (.38 mm) - tough old standby, wouldn't hesitate to use this for drum, carry a spool for backup
Wychwood DPF-18 in 18# (.35 mm) - a pal sent me a spool of this to try...it is from England...tough, tough line, low stretch...BUT...it is not in a bright color...and expensive...I have it on one rod and am going to use it until I catch...
These are the lines I currently use. I buy them in 1 or 3 lb spools and change line often. If I THINK it might have a slight nick or abrasion...it gets changed. I'm not gonna risk a huge fish on suspect line.
All of my leaders are Berkley Trilene Big Game in clear. I use 50# for shockers and 80# for a 4-5' bite leader. I make my bait rigs out of 30 or 40 lb. I think I talked about hook leaders in the thread on hooks.
I guess we can talk about knots some other time.
