"Feels great and hold tension much better the alu power"
"Feel the pop and the pace."
"I bought 4 rackets, 3 pair of tennis shoes from Asics with competive prices compared to other sites and perfect service. I will be back :-"
"I usually use Prince synthetic gut duraflex gold 16G for my racket. This time I had to purchase Luxilon since the brand I like was not available. Luxilon is not as good as Synthetic gut string."
"I used this string in a Wilson 6-1 95S. The string in combination with the racket gives an extremely good feel and control. The string is durable and loses litte tension over time. I would recommend this combination to everybody."
"IS OK"
"These strings are so far my favorite tennis strings when its set at the right tension which is around 48 lbs - 50 lbs for me. I just love the feel whenever i swing the racquet and it hits the sweetspot. Feels great with the Pro Staff 90 at a low tension."
"The strings are a great match with the Wilson 99 LS racquet. It gives me a combination of spin and power as well. . . good balance"
"I really like this string. I have a full bed in Wilson Blade 98S. I get good spin and durability. I do not have any arm problems with this one. I wish it came in different colors. Maybe it does now. But that would be my only request for this."
"4G is a very low power string. As such, you need to be generating a lot of racquet head speed to take full advantage of the string. It has good durability and very good tension maintenance making it a good option for super open patterns like Wilson S series or Prince ESP frames. I did not care for it in a full set, Not enough power and spin compared to my usual setup. It does work well as a cross in a hybrid though. Gives a nice crisp feel and maintains tension well. The other big factor for me is price. There are other similar performing strings on the market for less and that is what would keep me from regularly using 4G."
