looking for some clarity

[Strike_King 609]

i just picked up a new duckett rod 7'6 heavy with a new quantum exo pt
6:6.1 reel put 30 pound powerpro braid i intend to uses this for swimbaits

kvd tour 5:3.1 on a 7ft st croix using it as my crankbait rod with 12 pound fluro

7:3.1 Kvd tour burner on a vendetta 7'3 rod use it mostly for jigs and frogs has 30 pound powerpro braid

i have been doing some looking around and cant come up with a straight answer some say a longer pole is better for cranks some say a shorter any insight on the matter would be great

so my question is if you had these rods and reels how would you set them up and with what size line fishing mostly central jersey waters and the river [smilie=throw.gif]
