Radiator suggestions please

I had my stock 2 core rad re-cored by a local shop with a high efficiency 2 core unit. I wanted to retain the top tank and couldn't install a 3 core as the botton tank was too narrow. I am running an 8 blade viscous fan, shroud, with a mild 360, 4 speed with a 160 t-stat. Temp on hot days would creep up above 200 on the highway w/the old stock 2 core unit. 2 hour trip back from Carlisle this year, w/outside temps in the 90's, the temp was stuck at 195 in the dead of heat for most of the trip. It did creep up a bit pullin a hill which is normal. Very pleased w/the results and still retained the stock appearing rad.
