iv always liked P-line products. i seen a compairison 4 years ago at the sportsman show and was sold .but they havent sold me on the hydrofloat .i exclusively use 40# power pro for fishing floats and have never had a problem if it starts to sink a little i just melt some canning wax dunk about 75-100 feet in the wax and it floats like flyline.and prevents it from freezing in low temps.i think its gonna take them a little time to perfect it like anything but im sure they will refine a very good product with some input
