Welcome Larry!
I have the MVP2, and I typically use EVODs, Protank2s or Nautiluses on it. Those are good tanks for *ME*. You can run your protank on the MVP. I got the airflow adapters because I don't like a super-tight draw. You cannot subohm on the MVP (well, some say they can fire a 0.8ohm coil, but I've never tried, nor do I want to push the MVP like that.) What are you looking for? Do you like top coils, bottom coils, something you could potentially rebuild, clearo, carto? There are so many choices out there, and what I like doesn't mean you will....
