Venus, below the Mystic (it's for lighter oil, but being a particle pearl, it owill still hook nicely. Clears heads more easily than the Mystic and does not flip nearly as violently. Wonderful ball on medium light oil!)
Horizon solid, above the Mystic (it will handle more oil and hook earlier than the Mystic)
Odyssey will be 1/2 to 1 full step above the Horizon solid, if you want a MUCH stronger ball, but it has an asymmetric core; so an extra dose of care is needed to drill it correctly.
