You don't really need two rods, you don't really need glass, and please read more than just one article.
I'm a huge Croix guy because they have a lot to offer. As of right now I have 1 crankbait rod that can 90% of my cranking which includes wake, shallow , squarebill, medium, and deep (up to 18ft) divers. That ranges from a Rapala DT-6 up to a Strike King 6XD. This rod is a Croix medium heavy moderate. Now they make several ones, the budget is the Mojo/Premier 7'mhm, midway are the Avid 7MHM or LT 7'8MHM. As this point I'll stop up the line.
But for the most part the Mojo 7'mhm/12lb line/6.4 ratio can handle just about everything.
