Redington was bought by Sage. Sage has a tendancy to underrate their rods and I assume Redington does as well.
Underlining a rod is a good way to gain distance, but not real good for a lot of beginners. What I would suggest is testing your rod to see what it really is and then try a line that is more suited for the rod and your skill level.
Save the WF8F for a point in the future when you become a better caster.
