For me Franklin comes into the team only as an allrounder if Jacob gives up bowling, im not sure I would have both of them in the team as allrounders with Dan aswell.
Flynn for me has a spot for as long as he wants it, I think he is a long term number 3 but should let him settle for a while at 5,6,7. I disagree with you Surge on How, I think he is an opener and we should persevere with him. Im a McIntosh fan, when he gets hundreds he gets big hundreds, 3 double centuries I think.
As to the role of a number 3 I think they need to be able to change a game, whether that be as a pure wall or as a strokeplayer, I think its Lawry or it could be Chappel always goes on about how a number 3 needs to be able to counter punch. I guess How could play this role but i quite like Ryder there, got two good starts last test but got himself out and got a jaffa. I think having Fulton breaking up the Ryder, Taylor, McCullum trio is a must (or Flynn for that matter). Needs someone in there to cool them down.
As much as I dislike redmond and think he is up to eff all I think he was starting to show something in the second innings in Brisbane, had done the hard work and was looking okay. Getting out caught and bowled in a test match is a bit of a no-no though.
