Would have like to have seen an 83 only 2D image. But, the 83/200 2D is improved in my opinion over 6.74 and other versions above 6.49. By that I mean I don't see "pixelation" in the 83/200 image. Hard to tell in an image that contains all three (2D, DI and SI). Would have been easier to tell if this was a full screen 2D 83/200 shot.
Not sure if it was the water clarity from various "junk" in the water (pollen, plankton, leaves, et al) or what but the water column in the DI and SI images on the 83/200 image set is cluttered relative to the 200 shot.
Don't see any noticeable improvements in SI, DI and 200 2D.
