I think it really depends on how loose the good player(s) are pre-flop. If they are fairly tight, I wouldn't mind them on my left, because they won't be likely to get involved as often. Since the fish are going to be playing a ton of pots, it is better to have position on them, so we're playing a lot of pots in position against them. The cost of this is that we will be playing a few pots out of position against the tight/good player, but that's going to cost us less than we should expect to profit from the fish.
If, on the other hand, the good player is loose and is looking to get into lots of pots with the fish as often as possible, we don't want him on our left. We're going to be playing too many pots with them or facing 3-bet/4-bet squeezes when we try to get into pots with the fish. In that case, we try to play with position on the good player, but this will still reduce the number of pots we can play against the fish because he's coming in more often when the fish is already in.
