haha yea sounds like it. From what I've read the shotlock is the best option for the MF. But for VS, it doesn't do crap.
Anyway, I found ANOTHER helpful thing for the VS battle with Aqua. It's called renewal barrier. You put up your shield and if he hits it you regain health (idk if u heard about this or if you used it, but it REALLY helps).
Now I can get a fourth of his health down. WHOO!!
Just gotta work on not letting my fingers slip. That's a problem I get a lot. Stupid PSP. =/
Ah well, it's still fun to play regardless.
