STOP!!! You can't rely completely on the GFs or you'll be sorry later in the game!!! Have you discovered the true power of Junctioning yet, because once you do, you'll go crazy with it!
Prioritize your Strength status, you should be able to get through using mostly attacks.
My first time through I only used GFs and Limits and I couldn't get past the Missle Base!

Careful now...
