Mono Vs Copoly Sensitivity

Recommended Posts

Which line is more sensitive:

15lb Big Game or Yo Zuri Hybrid 15lb?

In whose hands is the rod? ;)

All personal preference, but probably yo zuri.

Great truth in that! I will take the copoly every time. Catt manages to catch a few fish on the Big Game though!

Big Game is fairly stretchy, more than Yozuri Hybrid it seems to me.  Less stretch = more sensitivity.  I think Yozuri has a small edge in quality.  If nothing else, it has better diameter consistency.   But Big Game is a solid line that has been catching fish for many years.  I use either/or without worrying about it much.

Explain please!

No line stretches until hookset ;)

My experience is the same as BobP's. The less stretch a line has the more sensitive it is. The difference is even more pronounced with a fly rod.

Ok I got a 1/4 oz bullet weight, a 3/0 hook, & a 6" worm, on mono.

I cast it out, let it sink to the bottom, take up slack, & a bass inhales it.

How does it stretch at this point?

Please explain how the impossible happens?

You can´t quantify perception so Catt is absolutely right, it depends of who is holding the rod.

First, I'm not so sure there are any true "mono" lines that use only one nylon polymer any more, so for all I know Big Game is also a copolymer in the strict sense.  Yozuri is a copoly that blends and extrudes nylon with fluorocarbon.  As far as sensitivity goes, I think nylon or fluoro lines which are more dense at the molecular level tend to be more sensitive and transmit vibration better than less dense lines, all other things held equal.  More dense lines also tend to have less stretch, hence my earlier comment that Catt jumped on.  I would expect in comparing equal diameters of Big Game and YoZuri Hybrid that the Yozuri would be a bit more sensitive in transmitting vibration because the fluoro it contains is more dense than nylon polymer.  This doesn't necessarily have anything to do with feeling a bite when a fish picks up your bait and actively pulls on your line.  We all know that sensing a bite is a lot more complicated than just using one line versus another.  But in the end, I want to stack things in my favor whenever possible, even if they are very small things.

The "line stretch" guys are the guys that have to look at the rod tip to see it wiggle to know there's a bite. "Soft hands" can detect a bite, stretch or not, blindfolded.

John, are you one of those "soft hands" guys?...

Not always, but I do feel the ticks in my arm bones, when it's calm. If it's windy, I struggle, though. I've heard others describe the same sensation.

You must have a mighty good rod that you are going to feel a difference between those lines. The only lines that make a difference in sensitivity is fluorocarbon and braid, but that only was evident when fishing deep, 15'+ as a shallow bite is picked up with any line.

Become a line watcher, clear or clear blue fluorescent works best for me. You'll catch fish that you'll never feel with any type of line.

Because you pick up vibrations through a line regardless of stretch, but better if it is more dense, but less stretch means the line will actually react (ie. line jump) which is more visible, or am I getting this wrong?

Pretty much. Can you feel someone tap on the other end of a vacuum cleaner hose? Can you feel it if someone plucks a guitar string? In which scenario would stretch make a difference? How about density?

While we can debate the question forever, the simplest answer is that there is no 'one' correct answer. Much of it depends a lot on how you define and try to measure sensitivity. Another thing to keep in mind is that the mechanical properties of the nylon-based materials will change when they get wet, so you have to define whether you are testing wet or dry, and if wet, what percent of moisture absorption we're talking. Again, this will likely vary by manufacturer and formulation. Plus there are the factors of tension, molecular density, diameter, line coiling, etc.. Much easier to just group them as a class of lines and compare against other classes (fluorocarbons, braids, etc.) generally.

I wonder why dry properties of any line matter at all? I mean, sometimes I fish for squirrels in the trees, but usually I go for fish, and they are under water.

Gee, I thought I could go five minutes without offending. Guess not.

LOL - :) - they only matter because many of the manufacturers and people who do tests tend to do them all on dry lines, so you have to deal with that when interpreting their results. Plus there is the fact that at least initially, every outfit you throw beginning any fishing day will have line that has 'dry' properties (unless presoaked or sprayed - KVD, etc.), and that line's properties will change (not fluoros or braids) throughout the day the more you fish them. Which all goes back to my point of not having an argument over it until you create the definition or parameters of which you judge....but I get your point ;)

I'm not telling what I "presoak" mine in…

The difficulty I have is, "less stretch = more sensitivity"

Mono, fluoro, or copoly does not stretch until adequate force in opposite directions is applied or adequate force in one direction while the other end is affixed to an stationary object.

A bass simply picking up a t-rig off the bottom is not enough force to cause line stretch.

Here's a little test I try sometimes (probably totally unscientific).

 

Cast your favorite bottom bumping bait (jig. T-rig, whatever it is) out to the depths. Don't count it down, don't watch the line. Can you feel the bait hitting the bottom? Through your rod? What if you hold the line between your thumb and index finger?
