It looks like silver AV switches are now default option in US, on separate order I got two Dominix V2 and Initiate V2 ALL of them with silver AV switches even I didn't order them specifically (so ALL my US sabers have silver AV switches without me specifically order them)
Beside this, I think you will consider following as a nice haul
Aeon v2 arctic blue - going to sell
Initiate LE V4 blue - going to use it for 1 hand sparring
INITIATE V5 green - going to sell
Dark Sentinel v4 red with windows - going to use it for youtube videos
Dominix LE v4 with windows green - going to use it for 2 hands sparring
No indication of what is inside so can't comment on special\not special color controllers besides arctic blue
It's been a loooong time since I have posted (like a year) but thought I would add my insignificant opinion. I have each of those hilts and I wouldn't kick any of them out of the arsenal. Then again, most of them I didn't leave stock. Some I matched them with their smaller or larger twin to make a daishō. The others I painted or added accents (and made them a daishō). The point is that just because you get a "boring hilt" doesn't mean you need to keep it that way. Use some imagination; make them your own.
That is all. Back to my hiding place.
