1). Pocket pairs (22-JJ) are the only hands with which i will call a preflop raise. With all other hands i will either raise or fold. Certainly there are situations where you are getting >4:1 and then i would call with a much wider range of hands, but in general does anyone think this is a bad idea?
This is what i have been doing. I was proposing an alternative to this strategy when i suggested that i might start 3betting all pocket pairs more often. I needed to make that more clear in the OP, my bad

Suited connectors are very profitable to cold call with in position, especially in Full Ring. You have to be aggro with your draws, though.
I had not considered whether SC's would be profitable when played this way. But, obviously an opponent is just as likely to have missed the flop as i was when he bets simply because he raised preflop. And i love raising draws on the flop. Thanks for writing this.
