Sunline: fluoro damage from backlashing

[Bird]

Wow, entertaining responses ?.

Years ago I spooled a baitcaster with Berkeley Vanish flouro carbon and promised myself to never spool a reel with flouro carbon......not even the wife's. Lol

 

I do like Sunline sniper for leaders.

Isn't it true that once Fluorocarbon stretches it doesn't return to its original shape?

 

A kink is "stretched" but only over a short distance.

 

A dent doesn't weaken metal, a crease does.

 

A kink in Fluorocarbon or Monofilament is like a crease to metal.

That's what I've always understood - FC doesn't have the 'elasticity' that Nylon does...so if it's stretched, it retains the stretch where-as Nylon has some 'forgiveness' and as long as it's not extremely stretched will (mostly) return to it's original profile.

I'm not sure what that stuff is good for... but it ain't good for fishing. Terrible stuff. Lot of phantom breakoffs.

Don’t be confused thinking Nylon monofilament or Copolymer monofilament lines are elastomeric they are polymeric. Elastomers are rubber, polymers are plastic, different properties.

1 property to consider is notch strength, neat Nylon (non filled resin) has good notch strength compared to Fluorocarbon. When FC get notched (flattened) it looses strength by a wider % then Nylon. Poor notch strength weakens the line when flatten slightly tying knots for example. Flattening the line by pulling hard on it picking out a backlash will weaken both mono and FC,  mono is affected less but still weakened.

This is why you should be aware of any line damage and change it before it breaks.

I use to get kinks in 832 and Power Pro on occasion after some of the more nastier backlashes. If I wasn't mindful of how hard I was casting,  the line would break.  It was one the many reasons I stopped using it as my main line.... with exception of spinning gear. I now have a love affair with Sunline Xplasma with FC leader. 

I've never had that problem in 32 years of braid use.

Which is why I cringe when someone is tying a Palomar knot by making a loop & pinching it to pass it though the hook eye.

I don't even do that with braid. Pass through, then back to make the loop for the MK knot I prefer.

This would explain why my Palomar knots are not worth two cents.  I have struggled for awhile to figure it out.  Thanks Captain Obvious.

Kinks! The very reason I quit backlashing. I don't know why folks still do it.

[newapti5]

Yes I believe kinks are fluoro's nemesis; that's also why palomar knot doesn't work well for fluoro. But if the lost strength percentage is worrisome, we could always upsize the line like pros do - like using 15lb instead when 12lb is the common case.

Vanish, as in the lure you are about to cast...

IMO 5% seems extraordinarily low. You'd need a lot of backlashes to weaken the line to the point where it breaks off on a cast.

That would be some trick kinking the line in the same exact spots each time you backlash...

Do not underestimate my backlash skills....nor my impatience in pulling them out

Would three 5% degradations within 12 inches of line still be 5%?  Or is it now some factor of 3 times five percent?  We need an engineer in here

Hmmmm.....40 years ago this month I was in a statics class looking at a problem similar to this.   Not long after, the university asked me to take a year or two off...lol
