I've been playing TW PGA Tour games on PS2 for years, and the only way to rack up Attribute points is in single player games (mostly on Tiger Challenge).
You're right, it would be nice to be able to use your own character with a friend, and have a level playing field, as it were. The only way my friends and I have been able to do it is:
1. Let the friend make his/her own character, and build up their own stats, or;
2. Don't use your own character, and both play as built-in characters.
Cheers,
Marvin
