I was advised by a good centrepin angler (chavender I think it was) to try some
Ultima Flo-cast line for trotting.
Its a bit like Marmite; Some love it and others hate it.
Here is an extact from the review link above:
"
Flo-Cast is a unique development in monofilament technology. The first line to be introduced with a hollow centre core and grooved surface, giving a line that casts longer, floats higher and is resistant to twisting and kinking."
I have used it on my centrepin and It does what it says on the packet, although I haven't tried it in extreme cold yet and it says something about losing some of its hollow advantages in severe cold conditions.
It has a slight increase in diameter (eg. 0.18mm for 4lb line and 0.20mm for 5lb line) however it floats high in the water and gives a reduced footprint, plus it's very pale pinkish hue makes it hard to see from below and makes casting a doddle and also mending your line is easier because of the ease that it lifts off of the surface. Plus it knots well using a 5 turn Grinner knot or a Palomar knot.
I use a normal mono line from the float down to the hook of course.
I have also caught some nice double figure Carp using it with surface baits on my local estate lake during the summer.
They don't sell it in some tackle shops and I had to travel to 'Walkers Pitch" tackleshop in Sandy Beds to get mine.
I still occasionally use Drennan Float-Fish especially in very cold conditions but after giving Flo-Cast a go I must admit I'm beginning to like it.
