Kingdom Hearts What change when you drop a weapon in the dive into the heart?

In KH, I know that picking a weapong influences your initial stats and the level at which you learn abilities, but what about dropping a weapon? What change if I drop staff or sword?

 

It's not just the weapon you choose, but the one you let go that determines your path. The weapon you choose determines what abilities you get, the weapon you give up will give you a stat handicap (Lower strength, defense or magic)

 

I noticed, the weapon you give up also influences your initial stats.

 

It changes the order you gain abilities and sets which stats will be your highest.

It's not as if they make much of a difference though, by the end of the game you'll be dealing massive damage with everything no matter what.
