In Vapor's testing the alternate inlet drops the flow from 1.38 GPM to 1.27GPM with a DDC 3.2 and thus slightly increases temps. While measurable, it's not noticeable. So if they release a version of the Kryos with further apart connectors and you want to use large tubing you might as well go for the "worse" version. 1/2" ID vs. 3/8" ID tubing might even make more of a flow difference than the inlet location...
