Re: General 4wt question.
Janus;
In hopes that everyone's "two cents" are adding up,so you can afford yet another rod blank, I'd like to throw two more of my own, pennies, at you on your question.................
Everything that's already been said has been really good, solid, advice for using a 4wt.
I'm super weird enough, to really love all fly rods from my 1wt. to my 4wts for local, small stream, fishing for Searuns. In these smaller, coastal, streams and even the rivers near me, a "long distance cast" is about 30 to 45 feet. On occasion, in the right "spots" though, I'll need to throw 60 to 70 feet to get my fly where it needs to be so the Searun can see it........laugh at it like hell........... then take a natural.
But, I still may need that distance at times, regardless. I've tried so many lines, on these "lightweights", I could supply a fly shop with inventory. However, that's also "how we learn things", someone told me one time!?
So, the last two lines I've tried, (and finally settled on as "the best for what I want"), on my lightweights have been AirFlo's "Ridgeline" in 4 wt. and the Wulff "Triangle Taper" in the same weight.
The "Ridgeline" added,( without my doing anything new)........about 15' to my standard cast on a 4wt. soft action rod I'd built. It's simply in just the design of the line's outer finish that does this, plain and simple.
The Triangle Taper, though is really my favorite because is casts with the weight of a WF line, on a light rod, yet due to its unique taper it presents and roll casts exactly like a DT line, which of course, isn't as easy to do with a standard WF.
Again, just another 2 cents worth, added to your rod blank fund!
