Over the past 12 months I've changed over from powerpro to the spiderwire stealth, don't be mistaken for the inferior standard spiderwire braid. The main reason is that it is thinner for its given breaking strain which allows lighter jig heads to be used on rivers due to the reduction in drag.
It seems to be standing up well to continued casting and I believe that it has a better knot strength than powerpro, even if its strength is overrated as its just as good at pulling snags to the boat and straightening out hooks.
By taking advantage of the diameter difference I'm using a stronger BS than Powerpro and getting at least the same durability from it.
