Well versus passive ones you can go with more honest line where you raise strong hands for value and limp weaker ones. It can work well as they are less likely to raise wide versus limp yet still give action to raises.
Now of course in bubble especially it's often not that deep stacked. So e.g. 15bb deep you probably want to open shove hands like 22-88 and good amount of Ax as postflop playability with those is often problematic but they are most of time +EV shoves. But then some KJ, QJ, JT, 78s might make sense to raise small or limp as you are not facing shove often. But versus more aggro you might want to shove those often as then folding them would be sort of disaster.
It's hard to define exact ranges as it's so dependent of exact situation in bubble. Like villain type, effective stack depth and stack setup. E.g. is BU 2bb, 10bb or 30bb deep makes it totally different spot even if blinds both have 15bb.
But in general you want to ask certain questions:
- is shove +EV?
- do you want to see flop with your hand?
- is your hand too good to raise-fold or limp-fold?
-how likely are facing raise/3bet that you cannot continue against?
At least few good questions. So if you have hand that is +EV to shove and you don't want to see flop then shove is likely clear answer. But if you have hand that is not profitable shove but has good postflop playability then small raise or limp is perhaps option.
Then there are often hands that are on gray area like some JTs that seeing flop would be totally fine but having tonfoldnit preflop would be disaster. Then all options might be reasonable but perhaps shove or limp more often preferable.
