i feel that when you raise, maybe even 3bet in the right spots, with pp's, you have many more options to win a pot.

-hit your set with an A or K up and string them along
-cbet dry flop with an A or K
-check into a passive opponent for a possible free/scare card

its no longer "no set, no bet" in a raised pot, but its easier to get it in when a 2nd best thinks youre full of shit.
