Right, this one’s already got people twitchy… 
There’s a clip doing the rounds of Tom Maker using a bright green mainline from Korda that’s apparently set to be released soon – and it’s not your subtle, washed-out “pond weed” green either. We’re talking proper, vivid green that stands out like a highlighter pen in daylight.
Which instantly raises the question everyone’s thinking but no one agrees on:
Can carp actually see bright green line… and if they can, does it even matter?
Some will say fish don’t see colour the way we do, that contrast and line placement matter more than hue. Others swear blind that anything unnatural-looking in the water is a bite killer, especially on pressured UK venues where fish have seen it all. Then you’ve got the Tom Maker argument – if one of the most consistent anglers around is happy to use it, clearly it’s not putting him off.
But is that because:
-
The line blends in underwater despite looking mad above the surface?
-
The carp just don’t care as much as we think?
-
Or because rig mechanics, location and feeding confidence trump everything else?
And let’s be honest… if you saw a glowing green cable stretched across your swim, would you feel confident casting it out on a clear pit?
Curious where people land on this:
-
Would you fish bright green mainline?
-
Do you think colour spooks carp or is it angler paranoia?
-
Is this innovation or just marketing madness?
I’ve got a feeling this one’s going to split opinion. Let’s hear it
