I use 50lb braid fishing off the rocks for everything and find it strong as hell, you have the odd occasion where you get cut off quick but thats with all lines. Find the braid to be very abrassive and have the fish to prove it. It also all depends on what you targeting off the bricks as fishing for hounds and spotties in some places mono is prefered as it floats more than the braid which sometimes sits on the rock causing instant cut off
