FF5 grinding and stuff

I finally got around to playing ahead a bit, and of course literally the first new area I reach has only two encounter types in it, one gives 2 abp and one gives 5 abp. Needless to say, I spent an hour grinding in this area and now have the X-fight ability on my main attackers. Combining this with my ninja class allows me to do ridiculous amounts of damage at this point in the game, because I normally get two attacks with my ninja ability so I now get a total of 8 using X-fight. I also found a really good grinding spot on an island south of the crescent one, where on the southern half of the island you always get into the same fight that gives 3 abp. It's a tough fight without X-attack and the Ninja's dual wielding ability because there's 5 monsters with decently high evasion involved but it's worth the ABP, and you get decent experience as well. I plan on using that spot for grinding to level 5 ninja and level 4 red mage to get dual wielding and X-magic abilities. I want to advance the plot just a bit more before creating a cut off point for me to reach since I've only got 30 minutes or so ahead of where I am now. But yea I'm already pretty much as far as I was ability wise when I last played FF5 on my GBA, except I don't think I had X-Fight and only had the double grip and dual wielding because I built my characters stupidly. I've still gotta work on my level a bit since I've been mostly grinding for abilities and not for levels at all and as a result I was actually kind of under leveled until I started grinding on that island. Now I'm around where I should be at this point in the game.
