I have both balls. Although they are drilled different the nature of each ball is still the same.
The AMB solid is a good ball for a oil especially with the OOB finish. It gives a strong reaction and carries through the pocket well. The AMB stands more of a chance in the heavy oil. The AMB with a light polish or smoother sanding can handle a medium oil condition very easily. The AMB gets a good solid reaction and has a fairly predictable transition to the dry.
The Frankie is a strong piece but is very smooth rolling and doesnt fair very well in the heavy oil.
I think with some minor tweaking this ball could fit nicely between your Violet and your Arc
