[Grammar] the most rational of decisions has or have

[hhs010120]

Hello, Teachers
Please help me out.
In the next sentence, are the underlined of and have okay?
[FONT=&#47569]
Even the most rational of decisions typically have an important emotional component, and many emotionally motivated decisions are quite reasonable. [/FONT]

Thanks inadvance

'of' is OK'; 'have' should be 'has'. 'The most rational of decisions' is a single decision.

I think "the most rational of decisions" can be singular or plural. Several decisions can be equally rational and can all rank as the most rational.

I quite agree with GoesStation.

I am not a teacher.

From the title of the thread, I went for the singular, but from the sentence, I agree with GoesStation that it could refer to a single decision or a bunch of them. The wider context would determine that.
