Its very easy for us to pass judgment on a company we dont run... Waterlooged, yes Feser may have used some questionable tactics in their marketing, however it may have been the product of an over zealous owner rather than a crooked minded thief. Thanks for pointing out the facts and insuring new users are made aware of the dangers in blindly following marketing hype, however there is a fine line between "informing the ignorant" and "beating a dead horse." The fact that you are bashing a company on a product not yet released leads me to believe you are just being a hater, which unfortunately discredits your credibility. Let the radiator get released and reviewed and let the facts speak for themselves. We might just be pleasantly surprised.
Looking at the design, I doubt round tubes will ever outperform flat tubes in terms of surface area. However, after looking over this great link/PDF:
http://www.wieland-thermalsolutions....ohrewat_08.pdf, I saw some round tubes with fins INSIDE. Im not sure how much this cost, however, this design could certainly rival flat tubes. However again, I dont think this alone will be able to surpass flat tubing to the point of obsolescence. Unless Feser is able to really really REALLY come out on top in terms of performance, or keep production cost down, I dont see this as becoming a new fad. I think it would have been better for Feser to keep the Xchanger and release this rad in conjunction, phasing out the Xchanger as the Admiral series becomes popular.
