Wild Arms 3 Upgrading question

Just a short question about it; in the end, what are the optimal upgrades on each person’s weapon?


I know Cyril’s FAQ at GameFAQs goes deep into this, but I have my own setup that’s much easier.

I go for power. Raw power, with a bit of Critical Hit on the side. Don’t upgrade anything else. Why? Because having 2 bullets makes it that much easier to pull off a Finest Arts as soon as possible.
