I read enough posts to realize I'm not real interested in defining a right or wrong. But people saying that overlining does not make a rod "softer" (or underlining does not make "faster") are telling only a half truth.
Rod flex and action cannot be separated from line weight differences in the way a rod reacts and flexes. Give me any weight line and any weight rod, and I bet I can throw a cast that is servicable, regardless of the combination. The key is that a certain weight of line and rod and rod action will require a certain casting stroke in order to cast a particular distance, under any given set of particular circumstances. If you are using too much effort to make necessary adjustments to cast your combo effectively in the situation you are in, then you have "improperly" lined your rod, period.
I regularly use a soft 5 weight to cast a three weight line. I like the feel of that sometimes as much as my faster 5 weight with the same line.
I agree with Jack 100%! Best post in this thread. Ready to throw away your Hack license Jack? ;-)
I’m getting lazy so I copied and pasted my posts from a past thread on this subject instead of rewriting it:
Here's my take. A 4wt rod is built by the rodmaker to cast a 4wt line which weighs (the line) 120gr @ 30' (30' is the standard measurement used weigh the line and rate it - not necessarily the optimum casting amount of line!). With that being said, 30' of 4wt line is roughly equivalent in weight to 25' of 5wt line (which weighs 140gr @ 30'). If you are making a lot of shorter casts on a smaller stream, you may find a 5wt line works better for you to load the rod and cast well.
Now, given the same set-up, if you are casting 30 or more feet of line (remember that's 30' of fly line, add in the length of the leader/and and the length of the rod and your close to a 50' cast) on your 4 wt rod, the 5wt line may be a little heavy for that purpose and not cast very well. It really depends on the rod.
For real long distance casting some may even chose to underline the rod to achieve distance.
With some rods or in some situations under or overlining works best.
The long and short - give it a try and see how it casts.
I hate most fast action rods...but I'm a fast action afishinado!?! Most FA rods suck (especially the cheaper ones) and are only suitable for longer casts or tomato stakes. Pick up a rod and peel off a length of fly line equal to the length of the rod and cast it. Keep casting and lengthening the line until you get out at least to the running line. If the rod doesn't cast well at all those distances, put it back in the rack.
Anyway, rod choice (and action) is a personal choice but many guys think fast-action rods suck because they never cast one that was designed well using high modulus graphite, or they just don't really like faster rods. Each to his own.
I will say there are many more choices of decent medium action rods out there if you prefer that type of action.
No doubt many of us have casting "issues"....lol. Proper casting technique is a prerequisite choosing the right rod. I agree that poor casting form causes many FFers to overline or underline a rod to compensate. Also, your rod preference may change after you develop or change your casting stroke and become more proficient.
The other side of the coin is many of the rods built today, especially the faster ones are often underrated. The CCS ratings used by rod builders bear this out. In other words a 4wt is really more like a 5wt. BTW, I'm talking "power" not action. Back in the day, most rods were had multiple ratings like 4/5 or 5/6. Rod mfgs should go back to those type of ratings IMO.
Think messing around with different fly lines and line weights is like tuning a bow using this arrow or that arrow, or this fletching or that fletching until you dial in the right combo to make your arrows fly well.
Most times I use the recommended line weight, but I do have rods that cast better for me over or underlined. Don't let the number on the rod stop you from messing with it. That dog rod in the closet my end up being you pet stick with some tweaking.....but don't expect miracles....lol
BTW, I agree with Pcray on the overlining of rods for small stream/short cast fishing. If you cast a fly with a lot of weight or a larger wind resistant fly on a short line, the heavier line is a great help to propel you line / fly to it's intended target Also, he made the point that many times you cannot get a proper or full backcast in tight quarters, and the heavier line helps in that case too.
Hey....just put a little tape over the line weight label on your rod and have fun!;-)
