I am about to go though the game again but this time am aiming for a complete run, weapons, dark aeons, penance, etc. In short I want to do pretty much everything that can be done with the likely exception of completing the sphere grid with all characters!

I've used the standard sphere grid enough to know whats going on and am tempted to use the expert grid now. I just have some concerns. Mostly I am concerned that the expert grid may stunt my abilities in the long run making it (impossible?) to kill penance (no zanmotos). Is this a genuine concern?

Apart from that are there any major bonuses to the expert grid? I'm really quiet happy with the characters styles as they are (I don't see auron as a mage) with the exception of kimahri who I'd like to customise a tad better than last time.

So is there any point in me using the expert grid or should i justs tick with the standard?
