I had the one out of the rear window to take the flasher out. It is back in there now.
I think the 600 looks better up top, besides the fact of it creating more distance between the cannons in the fogs, it looks visually more appealing- atleast to me.
and I know you've said in the past that you're not a fan of a lot of white light to the front, but I think a pair if takedown spaced out far from each other would look nice, even if you didn't run them at night I think the slow wig wag of takedowns during the day time is very eye catching.
if I were you I'd set it up so itd be TDRRRRTD and keep it on the same flash pattern it's on now with everything synced except have the takedowns on opposite circuits so when the right side red flashed the left takedown would flash and when the left side flashed the right takedown would flash and somehow still have the ability to steady burn them incase the need for scene lighting or anything like that ever arose
just my .02
