The Gaia IIs were what I tried. I didn't get the 1 because of the doubling of price, but if you are going to go the Gaia route I think that the 1 is the best and right option for the DI as well as the heavier SE.
I did not perceive any real differences or upsides with the Gaia II vs my doubled Herbie 'sandwich' setup.
