Understanding The Line or Rod Classification

The first thing to understand about line classification is to understand what Power Line Rating is.

Power line rating is poundage written on a rod and each rating has its own class. Rod produced by/for US / Europe market usually use the lure weight but this rating is used in the past (still is) and then line poundage was introduced for easiest universal reference. Below are standard ratings for rod & line:

1) Ultralight (UL)
– Not more than 6lbs.
– Examples: 1-3,1-4,1-5,1-6,2-4,2-5,2-6, 3-6,4-6

2) Light (L)
– Not more than 12lbs.
– Examples: 2-8,2-12,3-8,4-8,4-12,6-12,4-10,1-7,1-8 & etc

3) Medium (M)
– Not more than 18lbs.
– Examples: 6-15,8-14,8-16,8-17,10-18 & etc

4) Medium-Heavy (MH)

And do also refer at others big player in the market like G-Loomis, Megabass, or any other brand who produced their own rod.

Now, you may be asking why in the market there are rods with higher poundage but labeled as “UL”? Honestly, it’s probably their trick to capture both ultralight and light market or for some commercial purpose. No matter what their reason is do refer ONLY above ratings for reference.
