Knowing that most video game tennis ends up at the net, I went with technical from the start and it has "served" (forgive the pun) me well. You don't really need much power in this game, it's all about placement and getting your opponent off balance and running around. I get my fair share of aces and shots that blow by them, but making the rally short because I returned his serve then only needed one more shot from the net makes the games go much quicker.
I went for a defensive player. i just got the game today. i bought the last copy from the only store that has the game in toronto
