True, but one year is a long time. I know of college players playing synthetics who don't break them for many many weeks, and I also know of club level players who break poly once a week. Hitting against heavy hitters at the 5.0 level for a year should at least notch a synthetic string to the point of breaking. I do, however, know personal exceptions to that rule.
