That thread that
@SteveI links to has tons of info, but I will just quickly say that I used this string for a couple of years and absolutely loved it for excellent tension holding, stable playability through 90% of its lifetime, good durability, and very good spin capability. The downsides are that shear breaks happen frequently for those who both swing hard and mis-hit (I'm the poster child of that) and that it is a pretty harsh string when missing the sweetspot, and that as I turned 60 years old, my wrist wanted a softer string in order to play without pain.
17 gauge is a much better string, IMO, than the 16 gauge which is just harsh and doesn't seem to add anything to offset its extra stiffness except for durability.
