I do 99% of my fishing from a kayak, so I typically carry four rods, but I'm looking to add another to my arsenal.  I've got several (cheap)setups, but I generally take the same four that I feel do multiple things well.

 

I'm currently using:

 

Ark Rods Invoker 7'1" Hvy/Revo STX - Frogs, Swimjigs, Swimbaits

Powell Max 3D 6'8" MHF/Tournament MB - Texas Rigs, Jigs,

Castaway Taranis 6'10" MF/Revo S - Plastic Jerkbaits, Spinnerbaits, Topwater, Shallow/Lipless Cranks

Dobyns Fury Spinning 6'6" ML/Pflueger President - Finesse applications

 

As you can see, I really don't have any brand loyalty at all.  I really enjoy using different equiptment. 

 

I'm just looking for a recommendation on what to add. 
 

I would add a medium powered spinning rod
