The Rhea doesn't actually require soldering as Dominik will do the soldering first before shipping. For sure having to know 20 versus 21 pin is a pain. But the Rhea/Phoebe have a huge advantage of being here now and known to be very reliable (they work flawlessly). Not discounting this new approach, it seems very promising, but just pointing out there's already a solution available today for those who didn't realize.
