I'll second Lee's thoughts, dropping one line weight isn't going to be much difference, then of course after the three weight, you're going to set yourself up for the 1 wt if you so desire and like Lee said, "you can fill in the gaps later".

Right now I've got a 5/6 wt and a 7/8 wt and going to get a 3 wt for the smaller trout streams we have here in the white mts. I had contemplated just going to a 4 wt and then talked to a few friends and they all said the same thing as Lee. I have since decided on the 3.
