But it sure does look nice; we are debating whatever to do custom or kit frame this year and this definitely is a nice reason to do kit.

#35 chain will be more forgiving of misalignment, though saying that it is better is probably a stretch in my mind.
The stack up of parts for each wheel fits pretty closely into the width available within the C-Base, so located everything should be pretty straightforward. The mounting plate that supports the transmission is the part that can lead to the most trouble and is, honestly, probably the weakest part of the design. I hope to provide an alternative gearbox setup using Super Shifters and eliminating that plate. I went down that route first because I started designing with my team in mind and making that part is trivial for us. Similarly, we have a lot of parts on hand for #25 chain and none for #35 chain.
That being said, the design works just as well with #35 chain. The AM shifters come with #35 sprockets anyhow. Replace the 36 tooth #25 sprockets with 26 tooth #35 sprockets (AM-0142) and the ratio remains pretty much unchanged. The IFI sprocket mounting hardware is all designed to accommodate #35 chain, so spacing everywhere should be fine.
Edit to add:
The AndyMark perforated sheet works just as well. The McMaster-Carr part number I included is what we've used in the past. It's also pre-drilled. It's PVC rather than polycarbonate as well, for what that's worth.
