best line with low sc? .25/.50 stars ring

[freshbeats]

this table is beyond tight - i'm seeing lots of flops and have generally been outplaying postflop for small pots.

... should i be raising bigger for value, and to try and prevent the overshove that i would feel bad about calling?

anybody want to comment on the line up to here? i thought about sticking in a bet on the flop, but the pace of the table made it feel like i'm getting raised there.
