Value from Top set

[TheFoxNL]

Last 2 days ive been hitting top sets like crazy
like i raise with JJ and flop comes 47Jrainbow
or i limp with 88 from EP and i hit 258 2 hearted board

and everytime i feel i play it sooo badly
getting not enough value
or just pricing people in


how would you play top set
against straight forward players not over aggressive or passive

so lets say youve raised to 150 at 25/50 with JJ from MP
and you got 2 calls from CO and BB
so the pot is now 475
and you flop 27J 2 hearts (you dont have a heart)

how do you proceed ?
