Reflo Power Line is the stuff I use for all my float fishing; I also use it for fishing the waggler and pole for Tench and floater fishing for Carp. I use it for both mainline (for use on my centre pins) and as a hooklength for other disciplines, the stated strength has always proved accurate, I have now used all the breaking strains from 0.07mm (1lb BS to 0.24mm (11lb BS).
It is a very good all round line for use as a hook length that has great durability, I have found the quality to be very consistent and it has proved to be rugged in situations where fish have fouled under water vegetation, as it does not break as easily or as quickly as other hi tech lines I have tried and it works equally well in both high and very low temperatures.
.
As with any line what an angler requires most is reliability and Reflo Power Line has proved this to me consistently over the last 3 seasons that I have used it.
Knot strength is very good, particularly with the loop and grinner knots and I find the colourless clarity to be a definite advantage, particularly when fishing hard popular venues or when I am fishing for clever finicky species like big Roach.
One last thing, I am not and have never been sponsored in any way by Preston Innovations, this is purely a recommendation from good experience.
