Ok Gents, nobody knows better than me that "need " is a mischosen word. My apologies for absentmindedly injecting logic into a topic mostly ruled by passion.
Still, I'm thinking that even a chronic rod hoarder such as myself can't find legitimate love for 4wts, I have to wonder if they are only of great value for the trout fishing crowd.
P.s For the record, I do own five four weight rods from 5'9" to 9'. They just rarely see daylight end even then only with a 5 wt line for the most part.
All good conversation for a cold winters day!
