Vibrating Jigs have always been a #12 lb. ~ #15 lb. FC or Co-Poly line deal for me , yet I notice a lot of Pros using #20 lb. FC line and wonder if such heavy line dampens the vibration / action of a vibrating jig ?

No, it just effects the running depth.

I am curious to know what weights they are throwing on 20# fluoro.   I've just started using heavier bladed jigs...it is certainly different than swimming a 3/8 across the top of hydrilla.

Technically, I think it would have to dampen it somewhat because the lure is trying to move more mass (+greater surface area, resistance) at the same “frequency” if you will, just like heavier line affects the action and movement of all lures. The bigger question is how noticeable it might (or might not) be to the angler.

I use either 16# Sniper or 20# Shooter for 1/4 or 3/8 oz chatter or spinner baits. 
Which I chose is totally dependent on cover. 
I feel no appreciable difference in either but I use 2 totally different rods.

Regarding the feel, the resonant frequency of the larger line is different.  More mass keeping all other things the same lower this frequency.  If the bait excites the resonance and isn't purely mechanical it could actually amplify it.  The other difference can also be the stiffness.  A stiffer line made out of the same material would have the capability of transmitting the energy better.

 

As for if it changes the actual vibration of the jig itself?  That is dependent on how much of the jigs action is related to it moving the line.  If this is necessary for the vibration then a stiffer line would reduce it.  Needing to move more mass would reduce it.

 

Either way, my guess is that it isn't so relevant.  The forcing function of the water over the blades is so strong at driving that the resonance and stiffness of the line is probably not so relevant.

Whew!

I should have waited for you to respond first.  ?

I throw 20 lb line on chatter baits mostly because I often throw the bait into gnarly stuff and I want to get my bait back.

*Great points - this was what I thought would happen ...

I used 30 pound braid last season with them and it worked well until about August.  Then I got snipped off twice by pike two trips in a row (lost 2 thunder crickets).  So I started using a 12 inch length of Seaguar Blue Label fluorocarbon.  I did not get trimmed off from that point forward but I was definitely more aware of the wear and tear of the line too and regularly changed it.  Losing 12 dollar lures will do that to a guy.

I dont think it matters as much as a bottom contact bait or finesse style bait.   I like them on 16lb Sniper. I've thrown them on 25 lb floor with no issues..

I tossed a lot a Jack Hammers last year and like others mentioned its not fun losing a lure that cost so much, even if you get them on a discount. After losing a few on 12lb Fluro I switched over to 20-30lb Braid and it worked great. Without doubt saved me quite a few lures. just my 2 cents, I am FAR from a pro on the matter lol

I just read an article where a pro was fishing 40# braid. He said it was very sensitive, if you think you have a bite just give a few cranks on the handle, because you can possibly be snagged.

I have used 40# braid on my 3/8 oz chatterbaits for the last 3 years.  I tried fluoro a few weeks ago and hated it.

Yeah I think the braid is much more sensitive. I actually noticed it when I needed to put new line on my reel. I use a cheap mono backing with the braid on top. Well I bombed a few casts that went into the backing. I could barely feel the vibrate while bringing in the mono, but as soon as it was the braid section I felt every little tick and the constant vibrate. 

Don't know, cause I don't fish chatters on light line. 1/4 and 3/8 mostly on 15 lb, 1/2 and up on 20 lb, BG of course. I don't like braid, but will use it in current when trying to keep bait down close to bottom, then it's 40 lb.
