Del Potro likes slower hard courts cause it gives him a rhythm.
A faster court would favour an out and out risk taker over him.
Yup, that and the fact his strokes aren't very compact, he can be rushed on very fast surfaces. The one player that would benefit greatly from super fast surfaces is Berdych imo, he's a beast in such conditions, Tsonga too to a lesser extent (his BH remains a weakness).
On those very fast surfaces, I'd agree that Federer has the best FH. Both Nadal and JMDP can be rushed in those conditions, Federer's the best weapon on such courts.
On the slow conditions we have currently, I'd take Nadal's insane spin or Delpo's unique consistent power though.
lol, caught my post before edit
he would do worse in 90s US Open, better in 90s French, worse in 90s Wimbledon, about the same in 90s australian (which is currently bugger all)
no real difference
although he's won the US, i don't think it's an exact natural fit for his game
australia is too slow, wimbledon is too movement hindered. french is a good fit, can see him winning there...one day
indian wells is the perfect fit for his game, surface wise
He can play well on all surfaces, even on grass now if the Olympics are anything to go by - he played some great stuff there.
I'd say the best conditions for him would be a medium paced claycourt and a fast (but not overly fast) hardcourt.
