Yes, Head did send both versions of the MicroGel Radical 630, the 18/20 and 16/19 to test, along with a MicroGel Extreme and Extreme Pro. But the MicroGel Radical 630 18/20 was the instant winner, clearly more similar to the E57. With more strings on the ball, the 18/20 played with more control, stability, and touch. The added spin and power of the 16/19 string pattern was a plus, but was not needed. The Extreme and Extreme Pro never really got much court time, they were quite different from what my son was use to.
