Same boat here.  I've got 3 rods that it wouldn't bother me to sell.  The rest I am keeping even though many won't see much use at all.  Just never know when the urge will hit you to fish one of them.

 

OP, go by the rule of 2.  You have a 4wt so go for a 6wt and 8wt.  BUT...I see nothing wrong with owning a 4wt, 5wt, 6wt, 7wt & 8wt...each in several different lengths.  Personally I've never had a problem owning more than one rod of a certain power and action.  Just take a peek in my basement.  

Agreed on that one.  I think I am up to 3 8wts, 3 7wts and a few 4s and 3s lol

 

easier to swap a rod than a reel when i want to go between sink tips and floating.

I have a limited quiver.  Three 8 wgts, three 6 wgts and two 5 wgts.  For bass and light salt water I mainly use a 9' 6 wgt.  Nice thing about tying your own flies you can tailor them to fit the rod you're using.  I fished that area once when I was down there for my nephew's wedding.  On one of the barrier islands, south of Charleston.  A lot of redfish in the area,  some that could put a good bend in a 9 wgt.  I use one specific 6 wgt and one specific 8 wgt.  The others are spares, in case I break one.  I would've kept the 9 wgt.  A fly rod doesn't take up that much room when packing.
