Go fly the Citation, if you can have them typerate you, the better.
Disregard captain M, he is obviously clueless when it comes to FAA regulations.
On a US registered aircraft, regardless of 1 or 2 pilot crew, you can log PIC any time you are the sole manipulator of the controls. You do not need a type rating as SIC, SIC typeratings do not exist acc to the US regs. The FAA is looking into changing it, to come in line with JAA nations, which require a typerating for both pilots if aircraft is certified for two pilots.
But be careful of birdstrikes in the Slowtation, they tend to fly up the tailpipe
