Red clay, and no, it's not cuz I dislike Nadal's gamestyle (which i REALLY REALLY do), I hated clay way long back when i started watching tennis in 1999.
I like agressive tennis, and yes, I like long rallies, but only due to both players doing an amazing job, not only because the court allows it (nowadays, more like it forces it).
This. Critics of aggressive tennis like to reduce it to its worst form (1-2 ball bashing, hit or miss, etc.), but the truth is that there's a clean and ugly to any style of tennis. The long rallies, at their best, are elaborate, methodical, and captivating. At its worst, it barely transcends keeping the ball in play and dull pattern tennis...
