"I am getting 4.5:1"

?? am i missing something? where'd the .5 come from?

"I feel the implied odds and reverse implied odds near cancel each other."

that's easy to say, but that's not the case here. your hand will have deception value. if the flop comes 772 no one will say oh joe must have a 7 when you start raising and reraising. it'll seem more likely you are in their with a decent pocket pair. also how bad your rio is is up to how well you play postflop, how well you read hands, and how aggressive the guy with the really good hand is (sb). reverse implied odds are avoidable to a great extent by playing great.
