Brassworks ‘28 Show Quality vs Active Driver?

[Mabel1930]

Hello all,
I’m about to launch into replacing the incorrect radiator in my ‘28 (while I don’t do shows, being a history teacher, I’m basically running a show car). Having searched the judging standards, I can’t seem to find anything about fins/inch and am curious on people’s takes on the show quality vs active driver radiators from Brassworks. I drive almost every day so I definitely need something that can handle serious use and I would like to be as close to out of the factory as possible in terms of the car being correct to 1928, but also of course don’t want to have to worry about overheating if driving in August. If course a 10fin will run cooler than the 6fin show radiator, I just don’t know enough about them to know how much of a difference that’ll be considering the driving I do (which is a mostly flat costal area in New England though every once and while I’ll drive up towards the mountains). Anyone have experience with the two styles?
Thanks!
Mark
