Mana eggs are the source for most of the magic attacks in the game, but which egg suits which character the best, do you think?

As it stands, I have the Soul Egg equipped for Ryudo (I tend to rely on his skills, so whatever egg he has isn't used much. The Soul Egg is a nice all-rounder), the Chaos Egg for Elena (because her regular attacks are weak, so she needs some attacking power - and her magic does most damage), and the Holy Egg for Millenia (a healer is needed, and I use Millenia's skills more often).

dragons egg for ryudo, holy egg for eleni(my healer), i dont know millenias but she can just use one of her specials and wipe everyone out:D

I give the Chaos egg to either Millenia or Elena! They have high MP and the magic on the Chaos egg is good.

So far where I am I have:

(Everyone's around level 31, at the point where Roan leaves the party after defeating the claws of Valmar)

Ryudo - Mist Egg (I just had to give him something... well rounded, with a maxed Howl and Howlslash, with a lv. 3 Howlnado
Elena - Holy Egg (She's my healer, and there's the highly useful Tremor and Quake there)
Millenia - Chaos Egg (Well, what do you expect? She's got a lot of MP)
Roan(when he was in my party) - Chaos Egg(with Elena there) He's the magic attacker, though I tend to use Snowball Fight!.... Holy Egg(With Millenia there. He became the healer then)
Mareg - Gravity Egg(Eh, suits him)
Tio(Haven't tried her yet.. Gonna experiment) - Chaos Egg (Now that Roan's gone....)

damn go for an all out offensive, but have one character have a holy egg or one of the healing eggs! ok here it is:the ultimate egg stratedgy:
ryudo:chaos egg
elena:mist or gravity egg
tio:dragon egg
roan:grav. egg or mist egg
mareg:.... sorry i really dont remember him... all i remember is GRAVITY EGG!

The choice of eggs differ on me... I'm playing this game again and again to find the ultimate way to do this... Part of it is how to equip the mana eggs... If I can tell more I might put it in my possible future walktrough!
