Steel leaders visible

Use those guys advice for a lot of things
Thing is mono weakens underwater so if they do tests after the lines have been submerged the results will differ so id stick to fluoro

Not necessarily weakens but does absorb more water than fluoro. Bear in mind water would also act as a lubricant of sorts.

That and sunlight

Something I have often wondered about is the strength/abrasion resistance of plastic lines in warm vs extreme cold temperatures.  Everything else made of plastic gets brittle in the cold.  I have never had an issue with bite thrus in the open water season....only ice fishing.  Never even had a bite thru on 40# flouro during the summer.  I wouldn't even consider using it in the winter.  Anybody else have this experience? 

My bet is that the guys using 20# flouro consistently without bite thrus are using it in open water.

Pike could bite through 100lb easily I believe its how you fight them and where you hook them

I dont get why bluegills get spooked off from steel leaders during ice but not during summer

[DR.SPECKLER]

I think its a metabolism deal.they are aggressive and eat ferociously in warmer weather and during cold temps fish tend to stare at a bait a long time and see wire.

Targetting other species when they attack my lure

This is almost like saying why fish bite a lure with a hook sticking out of it...
