Line rating on rod

Nothing, as long as the drag is appropriate for the line rating of the rod.

 

Hey Joe! Remember the weakest link is going to give first. Make it your drag and all other links will be fine.

Joe I know you’re not thinking of 50# line on a trout rod. So if you keep it reasonable you’ll be fine with the appropriate drag setting.

Geez, everyone knows 'Never exceed the rod manufacturer line rating'

First fish on, rod going to fecking explode...

 

First 3 guys got it right. You won't be able to pull any harder if the drag is set right so the only advantage the heavier line will give you will come in the form of abrasion resistance

 

At the loss of spool capacity
&
At the loss of casting distance with the heavier line.
If not casting........no loss.
