Congratulations! It is fun to string your own racquets. Especially if you string one racquet-model, and using one type of string you will find your preferred settings on a lock-out. If you find the result too loose, go up in pounds; if too stiff, go down.For me the point of the exercise is to string racquets to a standard I find acceptable. The LO does that for me.
Problems rise when you have to string with different type of strings, on different racquet-types. Yes, you will find "the" settings for all those combinations, but that can be cumbersome and time consuming.
