I have been loyally using the PSGD since long ago. I absolutely love the feel of the strings. One thing though, is that they don't last as long as I thought they would. However, for the cheap price, you can't beat it.
Not much I dont like about the string. Hits nice, good spin, and lasts for a few weeks of hard hitting.
I like it because it is cheap and has some good feel.
I tried various types of strings since I started to play tennis. I had tried the super expensive and the relatively inexpensive strings. The Prince Syn Gut is by far the best strings. I mixed this string with the Tecnifibre strings to get the power and touch combo that many intermediate players like. For $5, y ou can't go wrong with this.
I string a lot of rackets for folks in my area. This is the most requested string even with all of the new string types available. It is very easy for the stringer and very durable and predictable for the player.
