Personally, I'd use the 7.0/7'MH set up for jigs, t-rigs, etc and I'd use the 6'6 combo for spinners. I don't like a fast tip for cranks but you could get away with them if you use mono. I would throw cranks on the m/f set up since it won't have AS much of a backbone to rip the trebles away from fish. For cranks, honestly, I would get a different set up, eventually with a mod action. Just my 2 cents. Hopefully its helpful haha.
