String is soft and responsive with good spin generation. The shape seems to be pretty effective. I liked it reasonably well but will have to admit that Big Ace Micro 19g has spoiled me. Black Fusion provides more spin and plays a little stiffer but I will stick w/ BAM for it's softer, more responsive feel and longer durability (I broke a BF main strung w/ 18g NRG crosses - that's never happened in a yr. playing w/ BAM). All-in-all, though, a pretty good string.
I tried these string after seeing the zoomed picture on the website. The design intrigued me. I'm hooked. Amazing spin and amazing comfort. Long lasting for such a thin string.
