Hey there! When it comes to materia management in Final Fantasy VII, I recommend focusing on a balanced setup for your party members. Make sure to have a mix of offensive, defensive, and utility materia equipped.

Prioritize leveling up your most important materia, such as Elemental, HP Up, and Magic Up. Also, don’t forget about mastering materia to unlock powerful abilities.

For specific character recommendations, I suggest giving Cloud the Enemy Skill materia for versatility, pairing the Magic and MP Absorb materia for spellcasters like Aerith, and using Support materia like Time and Barrier for well-rounded support characters.

Remember to customize your materia setups based on the mission or boss battle you’re facing for the best results. Good luck!
