OK, after reading all the related threads, I'd still recommend the Colossal. @prcgis correct about all ⅝ radiating pretty much the same. The reason I recommend it if some says price is no object is simply the durability. A friend back in Houston has one of the early models that's been through Rita, Ike, and Beryl, along with a derecho. It's still working great after all these years.
