Welcome sbt!
I'll 'tackle' one of the recommendations; I'd get the 7', MC(Medium Caster) Helium for Senkos, light T-rigs, and spinnerbaits. I have three of those models and I also use them for topwater baits, cr/baits, and hard jerkbaits.
I just received an Extra Heavy(action--not weight

) 7', 6" Helium but I havn't been fishing yet. I plan to use it for pitching/flipping heavier jigs, swimbaits, and C-rigging.
I think you'll be truly amazed at how much the strain on your casting arm(and neck) is reduced compared to using a conventional rod. Be sure and let us know your experience with yours when you get it and.............be prepared to buy another one
