I have a love/hate relationship with blood run. I’ve been running it (15lb) for a year now. It floats very well out of the box, allows you to fish across a fast current very well with some mending. It does kind really change the way you fish. But I have had it break regularly before 8lb leader, at least a dozen times. It’s strange the way it looks when it breaks, too - all frayed out. The second point is that its kind of flat in its shape, so if you are new to casting and get some line twist (or even wind) coming off the reel it binds up and sort sticks to itself, which can take several minutes to sort out. Can get frustrating after a while.
