Hey everyone! Here's a little bit of information. I used to play alot when i was younger up until summer of 2000, HS tennis 11 years ago with a prostaff 6.0 85. The only strings I have pretty much used is the NXT both 16 and 17 strung at 60lbs. A month ago i started playing again. I bought the blx six one tour and strung it with nxt 17 @ 55lbs. ( I feel older so I decided to lower the tension a bit lol) Just like back in the days I broke it after 3-4 hours of playtime. I feel like everything was once was back in the day so I went ahead and strung it this time with nxt 16 and went back up to 60lbs. Same story the string frayed and broke within 6 hours at most. Searching for a durable string directed me to TW and luxilon Alu power being a popular poly set up so I gave it a try. I had it strung at 60lbs ( I didn't follow -10% but oh well) the string felt ok. I still have it on my racket after 8 hrs of playtime. Now I must say reading this forum is new to me and I am more than willing to try any set up. I bought my own stringing machine aswell. I do play all around. I Used to volley alot but recently been staying in the baseline until I get back to where I was once at. I hope to find a string for the six one tour that has a great feel and durability that wont break my pockets as much as the nxt which pretty much has to be strung as often as I play. I don't even play games. I have just been practicing my strokes rallying and doing drills with pretty much anyone willing to hit.
