We can help, but here's the thing, it depends on what your definition of control is.
First of all, no string is going to do anything for your right/left control. That is a function of your swing and your timing at impact. Depth is another matter.
For many, control is not hitting the ball long all of the time. If you are hitting the ball long frequently, there are several things that could be going on.
- Not hitting enough topspin.
- A racket that is too powerful.
- Strings that are too lively.
We'll skip #1 for a moment and go to #2. If you are using a large, oversize headed racket, it just may be too much racket for you. Large head rackets are designed for players with weaker, shorter swings. Sure, you can put a really stiff string in it or max out the tension, but you'll never really change that the racket may not be ideal for you.
As for #1, topspin can give you much more margin for error. Topspin is a result of taking the right kind of swing. You can use a spin friendly string, but that is only going to help so much. The best thing you can do is take a few lessons with a good pro who can show you how to hit more spin the right way.
The funny thing with strings is so many of the characteristics that help with spin potential also make the string bed more lively. Playing with a string bed that is too lively will help send balls long. The better your technique is for creating topspin, the less likely you are to hit the ball long.
Now, if you hit the ball flatter, a lively string will give you little margin for error where depth is concerned. Going to a firmer string will reduce the trampoline-effect at impact and give you less depth, causing fewer shots to go long.
It is a balancing act. You don't want to go so firm that you can't hit shots deep enough. Find a string and tension that gives you enough depth on well-hit shots, with the fewest number going long. Also, a string that offers too much "control" will reduce the power of your shots, making them easier to return.
There is going to be some trial and error involved. We can show you some options that will offer the best depth control with the least sacrifice of power. Stop in and we'd be glad to help.
