My favourite string. Shifted to this string 6 months ago after reading a lot of reviews and recommendation and stayed with it.I string it at 48 lbs in a Wilson Blade 98. Gage 16L. Comfortable set up. String lasts good 12-15 hours before losing tension and significant notching. This is at the upper end of polyester strings for me in terms of longevity. I also like Volkyl Cyclone but in my experience the control is better with SOLINCO Confidential and hence it is my top string these days.Highly recommended. Try it if you are looking for more control and if you want to take full swings. Great spin as well for me.Finally it will depend on your playing style and what you want out of it. It works great for me. Also not as expensive as some other polyesters like ALU power and RPM blast.From stiffness standpoint it is between SOLINCO tour bite (stiffest) and hyper G.
