Geoff,
Both the Jupiter, and the old Auricap would take you in the right direction. The Mundorf EVO/Oil would as well. It is a matter of how far do you need to go, and how refined. This has to be leveraged with the budget as well. Correct, the cap I am referring to is not the G1, G2, or Plat. When/if you are interested, send us an email through our site, and I'll make them available. They will likely not be released for another month or two.
