My arsenal pretty much goes as follows:

Plastics(Texas Rig) and jigs- 6.5' casting rod, med-heavy action, light weight graphite blank(G.Loomis IMX, GLX or Phenix PX-1)

Drop Shot- 6.5' casting rod, medium action, light weight graphite blank

Spinnerbaits, buzzbaits, large topwater(Super Spooks, Prop baits)- 6.5 - 7' casting rod, med-heavy action, medium weight graphite blank(G.Loomis GL3)

Small topwater(Ricos, Poppers), soft jerkbaits, hard jerkbaits, Senko - 6.5 - 7' casting rod, medium action, medium weight graphite blank

Crankbaits- 7' casting rod, glass or composite graphite/glass

Vertical Drop shot(fishing off your fish finder) 6' spinning rod, medium action, light weight graphite blank

Remember, you don't have to break the bank with every rod you buy. Most of my non-feel presentations(reaction baits) are with rods that aren't necessarily the lightest, most expensive on the market.
