Re: he used a 3 way so I will too??????????
Moose: Great info on refractive index. So what line really has the same RI as water?

[QUOTE=Moose1am;309363]If the action is that much different using the bobber tied to the line vs squeezed in place with the plastic peg then I'll be surprise. I just can't see there being that much difference in the bait's action between the two rigs.[/QUOTE]
I haven't fished FnF either, but I would not be surprised if the action is significantly different. Like you, I've done my share of fishing using a slip bobber, sometimes with a jig, but more often with live bait below it. One of the things I've read about FnF fisherman doing is taking the slack out of the line and giving the rod a good shake. The wiggling gets transferred down the line to the bobber, which will move back and forth, and in turn wiggle the jig. You can sort of do this with a slip bobber in place, and I do it occasionally, but the line moves up and down in the bobber, acting as kind of a shock absorber, so the jig itself moves very little.

You don't need a microscope to see this. Just place the fishing line in the water and if it vanishes and you can't see it anymore it's probably got the same or a close RI.
But put on a pair of swim goggles and do this underwater.
I'd have to test some fishing line to determine it's RI.
I really don't know the RI of the different fishing lines to tell you the truth. It's been a long time since I played with the PLM and did these tests.
Most monofiliment lines are pretty transparent.
Even if the fish can't see the fishing line I would bet that they know something is there moving though the water as the fish have those lateral lines down each side of the body. Those lateral lines detect different pressure waves in the water and since they are in pairs they probably can also tell the direction the pressure waves are coming from. Much like the Lateral Sonar Array that are on the USS Virginia Submarines today.
Flurocarbon lines appear to be very clear and I would guess that they are very close to the same RI as pure water.
All my work was done with various oils that had different RI's. There are six different forms of asbestos that were federally regulated so I concentrated on learning the RI of those six different crystals. RI was not really one of the tests I performed. But I did use the physical properties of the Oil's RI to help see the asbestos crystals better. If you put a asbestos crystal with one RI into a oil that has a very different RI then that makes the asbestos crystal stand out like a sore thumb. It enhances the contrast making the crystal much easier to see.
I would guess that fishing line that's much different than the water's ri would also stand out like a sore thumb.
I don't really know if they can make a plastic that's has the same RI as water but they may. I just don't know the answer to that question.
Maybe later on I will research that question and see what I can find out.
