Pictures to follow Chris.
Final analysis is.... the original Pluto with 532, 445 and 637 is sharper and whiter that the direct diode combination of 520, 637 and 462. At least in mine. The all diode projector is now much improved with replacing the green but still doesn't hold up to the original. 520 green is more green than the 532 which convinces you that what we've looked at all these years is more yellow but, that's not a new revelation. Side by side you see a difference but, if you saw each one independently it's not that apparent. 445 and 462 on the wall is not "that" considerably different. Yes, it's more blue but I put some blue cues up on the wall and many were very close. The big difference, and I saw this with Adam's when he had them here a couple months ago is in the beams. 462 in the air is much more blue side by side and 445 really looks purple. The all diode projector does produce some shades of brown that the 532,637,445 just can't produce.
In the end, I'll probably buy one more all diode projector at some point with the 520,637, 462 just so I have a pair but, I think my personal preference in most cues is the 532,637, 445 combo. The quality of the white and the overall sharpness is winning out over the novelty of having water or American Flag blue in graphics. I'd like to see a module with 445 and 462 combined and I know some people are building them.
Off to take pics...
