NaeKuh: let's say, that with insane rad area MoRa more then makes up to it's shortcomings of using round tubes. And even while two common triples might cool with similar efficiency, two externally mounted triples with extra interconnecting tubing imho will look less neat then single MoRa on case side, even worse so for three external triple rads. So overall i still see MoRa as competitive product with it's own niche (i'm too lazy to compare pricing, how much MoRa3 vs 2*RX360+2 extra fittings cost).
As for feser rads .. it's hard to compare apples to oranges regarding their internal tube structure .. yes, they are also round shaped which is less efficient, but they also have internal fins, not smooth internal wall surface .. so at the end it might compensate that aswell.
I hope TFC will hurry a bit with admiral release, not to consider purchase ones, but to finally end with actual test numbers all arguing/speculating lasting for many months, be them worse or better then for common rads
