Comments: Strung at 55 lbs on a Babolat Pure Aero (285g). Durability : Lasted 6 hours of intensive rally. There was very little tension loss. The spin was excellent from the outer nylon coating. Requires hours of stroke adjustment to gain power and ther was great control as the string pockets very well. My conclusion, the CX fiber complimented the nylon in durability and tension maintenance making it the almost perfect tennis string. It gave me that crisp and soft pocketing feel of a nylon and at the same time control like a polyester. Tennis has never been this fun.

Comments: I just strung at 62/60 and practiced my serves and so far so good--nice pop to it and it was easy to string. I do realize I do not like poly's at all but will continue to test for USRSA when I get them however--the price is quite reasonable too and look forward to demoing my groundstrokes.

Comments: I put those strings for our top club player (all around style) on his K-blade Tour. He used to play with NRG, also strung by me. I set tension to the same 52lbs(calibrated) on my Gamma Progression. He gave his choice to Gosen over NRG. Price was not a factor as I charge him same for both strings.

Comments: This is not a multifilament string look at the picture it has a solid core.

Comments: Nothing spectacular. This string felt extremely underpowered for a multifilament. It gave a soft feel as the ball felt like it sat in my string bed even longer than it would on expensive multifilament strings such as Wilson NXT, and prince premier. In terms of spin it is all player generated, however it did not have the ball dropping properties of a polyester. It felt like I had to really muscle the ball to spin or hit deep.

Comments: I agree with Nick's review. This string is crisp, comfortable and resilient. It has really good feel, and it doesn't move much. This string is low powered, but the control is excellent. It is a definite upgrade over the Gosen OG Micro line of strings and is very reasonably priced.

Comments: This is a very underrated string. It's easy to string up, and for a multifilament, it has similar durability and tension maintenance of a poly. Not many multis can say that, and yet it has the feel and resiliency of a top-end string at a great price too! It is crisp and comfortable as an all in one string job, and it also makes a great cross combination with Signum Pro Poly Plasma Pure Hex mains. Try it and discover a secret gem of a string.
