It's on Sea level and right on the sea shore. SAF is an unique country - J'burg & Centurion are over 2000 metres altitude, Cape Town & Durban on sea level, East London & Port Elezabeth on sea shore but on small plateau.
Cape Town is probably the best place for playing spinners. Can say before watching the color of wicket, but if it's brownish, I probably'll drop Hasan for Abbas and rest remains same, or may be Haris comes back for FZ, which should help bowling as well. Fahim should play at J'burg, where don't think Yasir has much role to play.
Have to say - IMPRESSED by Shan. Hard wok indeed pays off something - Umars (Akmal & Amin) need to watch this game closely - these 2 (3 actually, Ahmed is the 4th one of that same group playing age level cricket between 2005-2010) has grown up from probably U13 level together and Shan was the least talented, least focused/talked about and least impressive at first sight, but looks like he'll play more games (at least Test Test) for PAK than other 3.
