The op picked two of my favorite lenses. My Rolleicord Triotar pics never gave me swirley backgrounds though, the Helios is the king of that, at least in my pics. The Triotar sure gave me some great portraits, much nicer than the "better" lenses because it isn't overly sharp until you stop it way down, and stopped down it is darned sharp.
I'd also nominate the Summar. Most people think they're not so great because so many of them have haze issues, but a clean Summar is a force to be reckoned with. Probably the best 50mm rangefinder lens I've ever used. Lots of character.
