Be forewarned, though. In our testing, we discovered that the Web Services protocol adds some 'wasted time' to all requests, and this wasted time slowly increases over the duration of the test.
It's not so big a problem if your response and thinktimes are high enough, but I've had some tests where thinktimes were driving the load and when wasted time exceeds a second and your think time is less than a fraction of a second it starts to dominate your load profile.
