Don't try to steal Economizers from Aquila in the Phoenix Cave. The enemy is a rare encounter, and the steal is a rare streal, and it will take far longer than it's worth. If you want an Economizer from Aquila, get it from the Coliseum. You can cycle back and forth between betting the Pearl Lance and the Strato to get guaranteed battles against Aquila without losing any items. Use Gogo with nothing but Capture, and he'll keep trying to steal every turn until he kills the enemy. Keep trying the battle until Gogo steals the Economizer.

I still recommend Brachiosaurs, though. Much easier, much quicker, and much more rewarding in other ways.

As far as Relm goes, she's as good as anyone else, HP/Defense wise. Defense is entirely dependent on equipment, and her equipment is actually really good(Behemoth Suit and Cat Hood make her a beast, and the Behemoth Suit is easy to get), and HP is pretty much the same for all characters. The only thing that sucks about Relm is that she has a crappy special ability, and thus is really only good for magic. But you can boost anyone's magic with Espers, and you don't need to boost stats at all to beat the game easily, so there's no point in using Relm(or any character) if you don't want to.

If the player only wants to beat the game, getting to the 40-50ish range is a breeze, and would probably take an hour at most.

If the player's only goal is beating the game, grinding at all is unnecessary. Level 40 is more than enough to finish the game without too much difficulty, and as long as you do all the sidequests, you should be there already by the time you tackle Kefka's Tower.

And you shouldn't be going anywhere near the Dragon Forest if you're under 50. Your first grinding spot should be the desert south of Miranda, where you fight Hoovers and Cactrots. These are easily killed enemies at any level, give you 10,000 gil per fight, and either 5 or 10 magic points, and the Hoovers give you a nice chunk of exp that will level you up sufficiently while you grind for magic.

Once you've gotten your magic learned and enough cash to buy whatever you need and some decent levels under your belt, only then should you try going into the Dragon Forest. And despite being easier, the Tumbleweeds just don't have the exp to be worth killing in the long run. And that one battle against 4 Tumbleweeds is the only battle in that area that is really exp. intensive. All the other encounters there are pointless. In the Dragon Forest, every battle is an exp. cow, and like I said, with the proper set-up and good levels, you can kill anything in there with only a tiny bit more effort than the Tumbleweeds, but with a massive increase in exp. You can doublecast Ultima to wipe out the T-rex's before the really do any damage, and Genji Glove+Offering is even more lethal. Really, the Dragon Forest is pretty much the go-to place for end-game experience in FFVI. It's what it's known for, and is where practically everyone ends up going sooner or later, if they intend on getting to level 99.

However, f you're only goal is somewhere in the 50's, the Tumbleweeds will work, but so will just about anywhere else, doing just about anything else. If you're a concientious battler and never run from fights, and try to get everything from every enemy and dungeon, you will be at level 50 by the end of the game without any end-game grinding.
