6.5 Better than OOTPBB 2006 for Solo Game?

[Murcer68]

I was waiting until real life rosters came out for OOTPBB 2006 before buying it, but after reading threads like these, I'm starting to think it isn't for me:

This game has serious ambition...but

Basically, everyone is saying the AI is awful in 2006, and I think AI is crucial when you play solo.

So my questions are:

1. Which AI is more realistic for roster moves (trading, free agents): 6.5 or 2006?

2. Would I be able to create my own 8 team league in 6.5, starting from scratch with a fantasy draft, using the real players in CubbyFan23's opening day rosters?

3. Does 6.5 include park effects?

I'm sorry if these are stupid questions - I'm just confused over which game I should get.
