Even worse than IW???
If it's so slow, how come Nadal has never won it?
The Miami surface is rated a notch slower than IW on the ITF surface ranking.
Wrt Nadal, it's all about the bounce more than the speed. He's done OK here, beat Fed in 2004 afterall when he was about 12, but just seems to struggle against the top guys every year rather than winning it.
