Wizard Ace/Five Count for Spanish 21?

Since the EOR for an ace in Spanish 21 is much larger than in Blackjack and nearly opposite of the EOR of a five, is it safe to assume that the Wizard A/5 count is more powerful in Sp21 than in BJ? Wizard, would it be possible to run a sim to find an optimal betting ramp for the A/5 count for Sp21?

Thanks.
