I'm actually the opposite. This is how I rotate my racquets:
I have 3 racquets. #1 has new strings, #2 is about a month old, and #3 is about 2 months old. I play with #3. When I break a string (or after a month passes, whichever comes first), I'll restring that frame, and I start playing with #2. When those break, I resting and start playing with #1. Next, I go back to #3.
The reasoning behind this:
When I restring, I string about 5 pounds tighter than I really like. After 2 months, the strings are where I want them. Because the strings have settled in, they no longer lose tension as quickly as when they were new. When I break a string, the racquet I grab has also lost most of it's tension, so there is not much of a difference in tension between the two.
Now, many people rotate their racquets much more often. They try to play with each frame an equal amount, and will string all of them at the same time. This also makes a lot of sense, because all of the racquets should be very close to the same tension, all the time.
I have one very big problem with this method: When you break a string, if all of your racquets have equal amounts of play, then you know that the other racquets are very close to breaking as well. I worry that my other racquets will not make it through the match. Also, when I use new strings, I can feel them losing tension the first time I use them. You basically have two choices: play with strings that are too tight the first time you use them, or deal with loose strings for the remaining time the strings are in the racquet. The tension between the first time you use the racquet is quite different from the last time you use it.
With my method, when you break a string, you have two string jobs with no wear - basically, brand new strings. You can be pretty sure that the other racquets will get you through the match, and then some. Also, there is much less of a tension difference between the first time you use the new strings, and the last time.
I'm not saying my method is better, I'm just sharing it. Both have their merits in achieving similar goals: Consistency. With my method, the tension is more consistent over the life of the strings; the other method is more consistent between each frame.
My method does have one other benefit: You always have three racquets with different tension - if the ball is flying on you one day, you can always grab a newer string job to get a little extra control.
@Djarvik:
What you described as "notching", in a racquet that has been sitting unused for a long period of time, is not really notching. Wheat you're seeing is actually the "memory" of the poly strings - their tendency to hold their shape, so to speak. It's more like a dent, and it's one of the things that makes polys play the way they do - they want to stay in the same position they have been in. This, along with the very low friction, is what causes polys to snap back into position after each hit. Notching only occurs when the strings have moved back in forth enough to actually wear a groove in the string. Notching normally occurs on the main strings, and very rarely on the crosses.
@KluddKalle:
If you liked the tension after the racquet sat for a long time, then I suggest you do one of two things the next time you string. Either use the method I described, or string looser.
