Hi,
Honestly, I would recommend dumping the Duralite regulators and the Matchboxes and going with a PowerSystem Eq6 but I understand your point. Keeping the Matchboxes will degrade your servo response, no two ways about it. Keeping your Duralite regulators will cause mismatched battery draw. If you want to keep your Matchboxes you could go with a PowerExpander Pro, if you want to get the best servo performance then go with a PowerExpander Eq10. Let me know if you have any other questions.
