After carrying a set around in my bag for the past 6 mos. I finally put a set of this string in one of my 95 sq in. mp 3i's at 58 mains / 56 crosses, and played with it over the weekend. This has to be the softest multi I have ever tried; I would definitely recomend it for arm/elbow/shoulder safety. It is substantially softer than either Tour Super 850 or the 850 pro spin, which have been my strings of choice the last couple of years. Although it is quite a bit softer than the Tour Super 850, I don't notice it being more powerful. They are all nice multi's, but I will probably continue to use the 850's as my primary strings as they both have a crispness(especially the pro spin) the 880 lacks; then on days when by shoulder is bothering me pull out my racquet with the 880 in it.
