I second that for the V7 18x20. Even better than the V5 that I used to use imo. Incredible buttery feel, predictable response, just the right amount of power. Mine definitely came out a little on the heavy side, but I came to appreciate that.
To the early question about 16x19, I demo'd it alongside the 18x20, and I was surprised by the difference. It was a lot tougher to keep balls in the court with the 16x19, and it felt less consistent too. And it's not as though the 18x20 is lacking for spin. Maybe my technique just doesn't suit that pattern, but if you had to choose one without trying before I'd definitely recommend the denser pattern.
