Dueck Defense RBU

You may have seen me post photos of my G19L with a Dueck Defense RBU with a Trijicon RM06 RMR.  Well Dueck Defense sent me another RBU, but this one accepts multiple RDS sights.  Now I have to figure out which micro RDS to install on this, compare to the RM06 and review.  Per Dueck Defense, this RBU accepts the Leupold 1 & 2, Doctor Red Dot Sight, JP Enterprises J Point and Burris Fast Fire 1, 2 & 3.  It also accepts Vortex's line of micro RDS's, like the Viper.  

What do you think I should get and test out?
