different stringing sistems???

[johnny]

back where i come from..... raquets are strung 40-45lbs. the gauge is about #18 - #22.5 on the adjuster.


the tension at 45 is pretty high and not soft for wussy players...

42lbs seem to be quite tight enough for most players and is the most popular.


also i've seen on some raquets with stringing spec....

8-9kg

25-29lbs

20-22lbs..



somebody plz explain..... why are there so many different stringing sistems..?


thank you for all contributions.

What racquets are these? I string my racquet at 30 lbs and it holds up pretty well. I know players that string their racquets up towards 40 lbs and break racquets readily, but they're sponsored so it doesn't matter.
