All good points. Remember that as you move up it is a lot harder to get your flush draw paid off when it hits, so the implied odds aren't always so reliable.

Re: small suited connectors and baby pairs, I also like to call a preflop raise with these. Though playing them in an unraised pot means you get to see the flop more cheaply, it's also less likely that much more money is going in if you do happen to hit big.
