All right, I've bit my tongue long enough.
Thus, over-lining slows the rod action AND makes it easier to feel the rod load. My point was simply that the dirth of fast action rods on the market and casting teachers who really only know how to cast fast action rods well is what is making over-lining so popular. And "old school" anglers are more and more finding themselves having to radically over-line modern rods (2 or more line-weights) to get the desired action out of them...especially for short-distance work.
I would argue that:
a) Casting teachers are not making overlining popular. Nor have I ever met a casting teacher who only had the ability to cast a "fast action" rod. Not that I've met them all mind you, I'm just very confused by your continual attacks on casting teachers.
b) "Uplining" and "overlining" only mean running a line on a rod greater than its rating, it doesn't mean people don't know how to cast and it's not any indication of experience or skill.
c) There is nothing radical about uplining for consistently short shots. In fact, it's just plain dumb not to.
Just passing along stuff I've learned from others .... Bruce Richards(CBOG) ....
Glad to hear you name drop on Bruce, you need to have a conversation with him on "uplining". There was at one time an exceptionally good post on this subject on Sexy Loops, but I can't access that site from where I'm at so I can't reference it. Nor do I know if it still exists.
I won't try to paraphrase Bruce but I'll try to cover the concept as simply as possible:
Let's assume that it would be ridiculous to try to always be exactly 30 feet from your target. I mean, what if you can't cross that current in that mountain stream, or you can't wade out to within exactly 30 feet of your target in the surf because it's too deep, or what if you are site fishing and there is a fish 15 feet in front of you and a wall behind you?
Imagine a world where you can only cast if the target is exactly 30' away.
Ridiculous, isn't it?
So what do you do? If the target is 40 feet away you might aerialize 30 feet and shoot 10. What if the target is 80 feet away? Well you aren't going to aerialize 70 feet and shoot 10, at least most casters aren't. You might aerialize 50 feet and shoot 30 though.
Well, surprisingly enough, 50 feet of fly line aerialized is going to load a rod more than 30 feet of fly line. Will you have to pause longer between strokes to allow 50 feet of fly line to unroll before making your next stroke? Well, yes of course you will, just like it takes longer to drive 20 miles than it does 10.
Did that extra line/weight/time make the rod faster or slower? I actually don't care, it's irrelevant to my reality of fishing and casting.
What is relevant is that unless you are always casting an exact amount of line on a specified rod you will never be dealing with a constant load on the rod. Another relevancy is that different rods will vary just how much load they need before they can help the caster (as a tool) direct the cast they need to, be it long, or short.
The majority of my time spent fishing is site casting to carp. The fish where I like to go are small carp, like 2-4 pounds average. There will be a few kicker fish to 12 pounds or so in the year, but day in day out the targets are 3,4 pound fish. A 4 weight is plenty of rod to handle the fish. A 4 weight line is plenty to handle the flies I throw at the fish.
Problem is, though, due to light levels, water clarity, necessity to cast accurately and quietly, I'm often making a 15-20 foot cast to these fish. Since my leader is 9 feet long and my rod is 9 feet long I'm often making this cast with only 3 or 4 feet of line out of the tip top. There ain't much to load the rod.
I can load the road by physically banging on it harder, but it is so much easier (on my body, and to lay down a fly quietly) to put a 6 weight line on the rod and use that. Am I uplined? Well, yes, by all technical definitions I am using a line over the rod rating. Am I loading the rod with the equivalent weight of 30' of 4 weight line? No, I'm probably still under a fair bit.
So am I a bad instructor for using a line over my rod weight? Am I an "old school" angler? Is two line weights radical? Am I using the wrong tool for the job? Are my casting students under priviledged because I only know how to cast a fast rod? Do I need to see a life coach over this?
I don't think the answer to any of those questions is yes. Well, I might need a life coach. If she's hot.
Again, the salient point:
The load on a rod is constantly varying. Even if you only cast one line on a rod, every millimeter of distance you change affects the cast. If you use different lines on one rod, the results will be different. There is nothing radical or incorrect about using different lines on different rods, and I would argue that in general, it's pretty hard to cast an under-loaded rod but you can pretty much add load (line weight, hand speed, fly weight, etc) to a rod to your heart's content.
Eventually if you add too much weight the rod will become just as poor a performer as if you were to severely under-load it.
This stuff can seem complicated, luckily our human brain pretty much takes care of the complication by shouting "more!" or "less!" to our muscles subconsciously. That's why a person with zero experience holding a fly rod can often, with careful instruction, make beautiful, effortless and effective casts within nothing more than a few short minutes. And of course, like so many other things in life you can never really stop improving or learning about your cast.
Audience note:
The only reason I took the time to post all this is because this thread has been full of over-generalizations of the kind that lead to additional confusion for most anglers. If anyone on here wants to really learn about casting, this is not the forum to do it. While everyone's heart is in the right place, the noise-to-signal ratio concerning casting runs way too high on the noise side here.
