Spell Speed?

I finished my gear setup between tome & current savage for scholar.
However, I also plan to try white mage as well which one build in particular has same gear pieces except for the ring, which isn't bad but my question is.

Should I change the meld setup or keep it where it's at? The changes would be somewhere around 6x rank 8 Heaven's eye(direct hit) removing them in favor of spell speed.
With the exception of one ring, all the other pieces will be shared between my scholar and white mage.

Spell speed greatly benefits WHM, I don't play SCH so I wouldn't know what their melds should be besides crit, Determination.

Spell Speed doesn't benefit SCH as much as it does AST or WHM. Personally a Crit and Det meld would benefit all 3 in equal measure.
