Just my opinions:
0. TE2009 is a lot more realistic than old versions (which makes me a lot more happy as well

1. Top spin: It is probably the most important strike to handle in clay court matches. I have heard from Nadal to get 4 meters high rebounces are not unusual in his clay matches!
2. Volleys: Yes, it is a lot harder to volley in TE2009, but I am agree that it is a lot more realistic (perhaps volley is the most difficult basic strike to learn in real tennis!). In the same way, in TE2009 is not so hard to make a succesful lob or passing shot than previous versions, where service&volleyers were too hard to win (unrealistically) in my opinion.
3. Two question to Manu:
Some times (not always) when I fail a strike, a red image with a player inside appears at the left bottom corner, and when I throw a ball out, a green image with the player and the number '1' typed appears....what does it mean exactly these spots?
4. When I choose and confirm my doubles partner at the first tournament of the tour, game often crashes, is this bug detected/fixed in last updates? (I downloaded the game last weekend)
Thks in advance,
