Pre-Flop shoving ranges: 6-max vs full-ring

The question is in the title. When you're down to 20-25, 15-20, 10-15 and <10 Big Blinds, what is a good shoving range?

I don't mean open shoving with these blind levels, particularly with 15 or more Big Blinds, but shoving over a raiser or limper(s) when you are fairly or very short stacked.

I would like to know people's opinions on these ranges in 6-max tournaments and full-ring tournaments and in what positions.

In 6-max games I am quite comfortable shoving with AT+, KQ, 77+ in any position. I would add suited connectors from 78+, any pair, any suited broadway duo and any suited Ace to this range in late position if unopened or if I had enough fold equity. Full ring, however, I am uncertain.

AT+ KQ+ 77+ is rather narrow. It's probably no more than 10% of all possible hands. I'd certainly shove wider vs a limper, and also vs most openers, the main exceptions being nits.

I'd also tend to lose the mid suited connectors. If you're called, you're better off with some kind of high card holding. SCs are hands to play when you can see flops inexpensively with them. Because you'll be well behind the large majority of the time, you need big implied odds to profit overall. The prospect of doubling up fall far short.
