Like anglerdave says, there is no right line for everybody. Probably, your best bet would be to go to your favorite fly shop and see if they have any demo lines reeled up for testing. Try them out if possible. That's how I found that an S/A Mastery Series GPX works best on my 7'9" 3 wght homemade slow action, and my 7'4" 4 wght Gatti fast action. Both lines are actually WF's. Good luck on whatever you find.
God Bless,
