If you limp small pp's, you gotta bet hard when you make your set. It's difficult enough playing sets for stacks after an open limp. You gotta bet every street (and you still need help).

Flying Saucy - in position, slowplaying sets in multiway pots on two-tone boards is bad, yes. But oop, if you're fairly confident of at least one bet behind, check-raising can be perfect. It allows the pot to build a bit, then you can force the remaining players to chase their draws at a premium.
