I need some advice. I want to order my pixel icicles from HolidayCoro.com either today or tomorrow. Their presale ends tomorrow at midnight. Each icicle segment will be 4' 8" long and is comprised of 20 horizontal pixels with each drop being 5 pixels for 100 pixels total. If you haven't seen my house i have one long 40 foot section across the front and that is where the icicles will go.

Now the questions. I don't want to do a ton of power injection. I will have a FPP with a PiHat feeding these 8 100 pixel segments. So obviously the FPP will be above the front door feeding 4 segments to the left and 4 to the right with one of them being reversed in XLights. I'd love to feed power at the start and end of each side of 400 but I'm not sure that would be enough power injection. That'd be going 200 bullet style 12v pixels before injection. Anyone ever done 200 on a run before? I mean I probably won't be doing much all white anyway. The other option is to feed in between segment 1 and 2 and then again in between 3 and 4. I'll represent this below for you:
100Pixels = Inject = 100Pixels = 100Pixels = Inject = 100Pixels = FPP = 100Pixels = Inject = 100Pixels = 100Pixels = Inject = 100Pixels
That was the most efficient way I could think of doing this but I'd be open to comment. I have a 6 port fused power distribution board and the PiHat has a buck converter so the PiHat would be feeding power to the first 100Pixel strings to it's immediate right and left as well. The four injection points plus feeding the Pi power will be five out of the six available ports on the power distribution board.
Also, I'd love to get away with one 350w power supply but it looks like that is just going to be just under what I need. From their website: 36 - 40 Feet: 8 Strings (432 Watts / 35.2 Amps) Thoughts? I'ts frustrating to have to add 4 injection points instead of 2 and to have to run two power supplies instead of 1. Keep in mind that I've found reducing my pixels to 50% power or even less doesn't have that much of an effect on their overall brightness. With so many pixels in close proximity maybe I could run them at 30%? Sounds like I'm talking myself into 1 power supply and injecting every 200 doesn't it?
