Just adding my own thoughts, been playing NL10 single table Rush pretty much since it started. My standard game is to 6 multi table NL10 on fairly standard BSS. So far imho:
1. I prefer it to multi tabling. You can quick-fold the trash away just like in multi but then s l o w d o w n again when you pick up a hand without worrying about the other tables. Concentrate on that hand, then back to quick-fold again, rinse and repeat 
2. Accumulating FT points with one Rush table seems only slightly slower than 6 table multi, think I read somewhere that it was thought to be about 4 times faster.
3. Not tried multi tabling Rush yet, not sure if it appeals tbh
4. Have really opened up my steal and 3bet range from MP3 to BU quite profitably. Play small ball poker picking up lots of small pots (c-bets get thru much easier) then tighten up considerably when I meet some resistance. Conversely over bets with the nuts getting called much lighter, eg 290 bb pot with FH v trips v flush, nice 
5. I tend to leave when I am 200bb+ rather than 150bb, there are lots of fishy stacks around 150bb but not many more than 200bb. Take the double-up and start again
That's it for now, really appreciate the community here for the ability to share thoughts.
