I like Honey.pro, good for beekeeping and people do this as a hobby, and want to be pros, and professionally, which widens your market for development or resale.
I also like HardDrive.pro, there is a strong association between Drive and Pro and it's usually hard drive related, the value here is a data recovery brand rather than the sale of harddrives. DataRecovery.com sold for $1.7m.
Note.pro is stronger than 2012.pro. Years work OK with .info because they can be used retrospectively but I don't think .pro carries it. Note.pro is short, brandable, flexible, you've got a $115,000 .com sale backing it up, you've got bank notes, notebooks, notes that you write as reminders, music notes, I like it.
I like the sound of Vodka.pro. It implies you make the best vodka and that you a pro vodka in general. I don't think you will sell this to a domainer or be able to develop it profitably yourself. You need to market it to vodka companies.
Upholstery.pro is a nice .pro. People want their chair professionally upholstered or reupholstered and it's a unique skill with a premium value attached.
Something like Mint.pro doesn't look useful on the surface but if you do a bit of research, Mint.net sold for $8,000 and redirects to Beverly Hills Mint Real Estate and even Mint.info sold for $691. Plus it's 4 letters and a colour which gives it standalone brandability. It would also work well for alot of collecting based hobbies where mint is the ultimate condition of something. Mint.pro would make a great brand for a coin or stamp site.
Vacancies.pro has a nice professional and hotel angle and is very logical, not a massive domaining word though and the "ies" plural hurts. Vacancy.net sold for $9,500. I hold Vacancy.pro.
