I think it's scary how firmly you state your case and provide some very dangerous advice for people who don't know better, because your case sounds okay on the surface.

To my right: All other aggressives, people who play extremely well postflop, people with lots of money.

Since they are tight, often it will be folded or raised to you. Since they are to your right they will often be in EP. Well, you are going to be folding most hands when they raise. When it is folded to you, you are in the situation of open-raising or folding. If you have made it so the people to your left are really loose, you can only really open-raise with legitimate hands and have to fold most of everything else, since they will be calling two cold and you can't take a shot at the blinds with weak hands anymore. Whenever you do play, you will often be essentially in EP. The tighties fold to you, the loose players all limp in, and your absolute position will often be terrible those times you are in EP and MP.

If you have tight to your left and loose to your right, you will be able to play many more hands because you will be able to see a multiway pot forming and be able to play hands like suited connectors and whatnot. Ocassionally, someone to your left will raise, but at least you have a multiway pot to make up for it. And the chances of you and a tight person being involved in the same pot are lessened since you are both tight.

You are often going to come in for a raise, and since you put tight players on your left, they will almost always fold to your raise. So now you always have position on the loose players, AND will improve your position or buy the button. And those times that you limp, since they are tight, your position improves often dramatically anyway, since they will often all fold. It is a rare event that you get 3-bet since there are so few legitmate 3-betting hands, plus we need the parlay that you get a raising hand AND the opponent gets a 3-betting hand. It just doesn't happen often enough for it to be a huge concern.

Finally, sometimes you will get one really weak limper to you, and you can start making raises with marginal hands to isolate the limper. It is much easier to isolate with tight players to your left.
