Is the "second bubble" a spot to make a play with a short stack

[DesertCat]

B&M Multi, 170 players down to eleven players. Two tables, I'm at the 6 handed tables. Second table gets $148 (buyin + $18). $16,500 to the first table, $340 to tenth place. So the next person out is on the "second bubble".

I have been the short stack for some time. I'm actually up to $15k, blinds 1.5k/3k. The loose big stack to my left just crippled another big stack by calling an all-in with 77 (the all-in had 44). The cripple is in the small blind with 4.5k, so he should only have 5 hands left.

Folded to me, one off the button (the loose big stack), I've got 66. The button has around $85k, the big blind around $25k. Should I try to back into tenth as the small stack? Or should i take this as an opportunity to build my stack before the tables combine, so I can make a run at at multi-thousand dollar payday?
