The 75/76 is kinda middle ground. The current bases are ATL, NYC, and LAX, so there is some variety, but not as much. As a general rule, getting into NYC is never difficult, as it is perpetually the most junior base. Again, there are never any guarantees, but virtually every bid has NH's changing bases down to the very bottom of the list to somewhere. And the vast majority of the time, you can probably get a base change on your very first bid (which if you are on property the day it closes, you will be able to submit for if you login).

One thing that bears repeating regularly is, there are almost ALWAYS awards posted in categories that have no vacancies posted. So, just because you don't see a vacancy doesn't mean you can't get it awarded. You have to bid it to be awarded it, so make them say "no" by including every option you can stomach in your bids.
