For me there are two options on the flop:
1) Decide you want to play for stacks right at this moment and make a conventional 60 ish bet, and jam 120 on (almost) all turn cards. There's 80 in the pot and we have only 180 behind, with this SPR we need to decide right now based on Villains if we plan on stacking off or not, before we are potentially forced to later on
2) Check the flop hoping villain shoves his remaining 60 in to the 80 pot on the turn. This way you can call on the button with ease and you should be way ahead of his shoving range on most turns. If another villain calls the shove then you have a relatively easy re-shove imo.
I think I would just bet the flop for 60, hope to get a call or two (or take it down right here) then bomb the turn on all none J Q or 10 cards, hoping to get a call from things like A10, any draws (if the players are bad enough) and expect to be good a lot of the time.
Playing for stacks is scary stuff, especially when we aren't at the top of our range, but due to the SPR I think this is a good spot to do so
Just my thoughts
