I'm going to change out the line on my Teton #4 to a DT line. I emailed Teton last week and asked the question, but no one ansered.

Anyway, how much backing do I add or remove to go from WF to DT? Teton states that the #4 holds 65 yards of 20# backing with WF4F.

Is there a general rule of thumb for this?

Regards,
