[BRENT in 10-uh-C]

I'm pretty sure the biggest difference between Bergbower's radiator's and Brassworks is Gery uses original tanks and straps on the Brassworks core, and Lee's makes new tanks, straps, and the core on his radiators. For the 28/29 cores, they will pass in fine-point and will cool very well. The straps on Lee's radiators are a tad different for the discriminating eye. My advice is choose whichever you prefer and ship your shell to whomever you have build you one so it can be fitted during assembly. You won't go wrong with whichever vendor you choose to buy from.
