Looking for suggestions for AP to run with Core and maybe APG only. Any thoughts?
For clarification - do you mean the adventure only uses core/apg or that your players are restricted?
If yes to the adventure - I'm pretty sure any of them up to Skull and Shackles (not including that one).
If yes to the second - any of them would work - they actually assume a fairly low power level on the players choice - you should find yourself able to run the adventure with little modification and still challenge the players.
