4wt is a bit light and a specialty rod. It doesn't handle bigger flies, can't handle a moderate breeze, and most don't have enough backbone to control larger fish. I know, because I was at a lake with fish 3-7 lbs and my poor 4wt (Winston IM6) was usually bent over to the cork most of the time. When the fish would sound to the weeds at the bottom of the lake, there was not much that I could do to turn them.
Since you're new to flyfishing and will probably be looking at one setup to do as much as possible, I would strongly suggest going with a 9' 6wt combo. Get yourself setup with two lines, a full floater and a slow full sinker. That will cover 90% of the conditions that you will want to fish early on.
