obviously there is no merit to your "due" theory. my proof is this simple: go find ten people who believe in this theory, and then ask how many of them are long-term winners.

as to your play, both hands depend on the looseness of the game. my inclination is definitely not to raise with big offsuit cards out of position unless i thought there was a very significant chance of buying the pot. in most tournaments, play is sufficiently tight that being in position on the flop is worth a bet or more in expectation, and you are going to hae to act first on each round. your opponents are also likely to pay you off on weaker hands if you do not represent strength early.

and yes, it is definitely inconsistent to raise with this hand in SB and not BB. think about it.
