Thanks for that!

I took out the most interesting parts.....this racquet sounds revolutionary for recreational players:

And what happens with the 16x15 pattern is that, compared to a 16x18, not only do the strings move a lot further, but they also snap back really violently. It makes sense. With less friction, the strings deflect further, and because they move further out of place, they snap back past their original position. Which increases the amount of rotation that the strings are able to impart on the ball.

Putting fewer and fewer cross strings does increase the amount that the mains are moving. But the big jump is between a regular pattern and just one less cross string, the 16/15. And as you go more and more open on the pattern, according to playtesters, it gets harder and harder to control the ball. So we think 16 by 15 is the right combination, even if you do get a little more string movement with even fewer crosses. With the 16/15, we think you benefit with the increase in spin without the negative of decreased control.

 We’ve found that a 16x15 string pattern has a more dramatic effect on players of average ability, actually. There’s still an effect for better players, but our research shows that it’s not quite as pronounced for them, as they’re already swinging so fast and causing the strings to snap back.

The snap-back effect, yes, it’s definitely maximized by a monofilament, a Luxilon-type string. You don’t see the effect with nylon or gut strings. They just move…but don’t snap back. That’s why players who play nylon or gut, they’re always straightening their strings between points. Which is why we’re hypothesizing that it’s the snap-back—the recoil of the string at a faster speed—that has more to do with the additional spin than how far the string moves out of place. At this point, however, we can’t say for sure.

Further to the point, people typically use examples of airplanes or cars when thinking about aerodynamics. But the problem is, airplanes and cars move in one direction; on the other hand, tennis racquets are moving in all different directions during the swing. Sometimes a racquet is moving vertically, sometimes horizontally. It’s just not moving in one direction. From our perspective, we haven’t found much evidence suggesting that a racquet’s aerodynamics can significantly influence players’ swing and spin production.
