I finally got out this last weekend and tried out the ballast upgrades.
With the dual pump configuration and the ballast springs removed I went from filling about 25 minutes fill time to 17 minutes fill time with the 1200lb enzo sac, 400 lb center sac, and about 250 in my bow sac.
I do know I want to upgrade to a integrated ballast bag.
For some reason both of my front sacs were full of air and took longer to fill initially. I'm pretty happy with the results.
