Hey,  I just bought some 10# braided line for Ultra Light applications. I have been using braid for years and know it will "dig in" from time to time. Other than this, with the 10 # be durable?

Sure will but don't forget to check often if your fishing in a rocky area.

I have fallen in love with 10# Power Pro on my spinning rod for just about everything.  Long, effortless, casts, no problems with tangles or line memory, seems very tough.  It is undoubtedly the best casting setup I've ever tried, even as good as 4 # mono, except much more forgiving.

I don't know if it is necessary, but I use an 8# fluerocarbon leader on it since I'm worried about fish seeing the opaque braid, and if you use a leader, you need to learn the double uni knot, which at first is tough, but with practice becomes easy.  And remember every other day or so, retie it as going through the guides can deteriorate the strength of the knot.

I have read that others use braid without leaders in everything except crystal clear water with no problems.  If tying directly to braid, learn the Palomar knot for your terminal knot.  Easy and will not slip.
