I was just recommending stacking the bags as a temporary solution.

It worked well for me today. When we switched to wakeboarding, I just switched the bag back to the other side. It only took two minutes.

The top bag didn't empty all of the way because the bottom bag sucked so flat, the pump couldn't pull anymore out of the top bag.

I may use this setup again, but still have plans to either get 1100 + 370 on either side.

Here is the port locker with the double stack. I guess it was 1000+ pounds.
