Deep water crank bait fishing for bass?

[FireMan]

Okay.I fish all the time and I mean all the time but my biggest weakness is in the application of deep water crank baits.I don,t even own but a few of them but it,s high time I learn.What are some of the best ones in your opinion and what sets them apart from others.Rod choice seems subjectional as well.A stiff rod or soft rod,what length and line dia. as well?Also,locating prime offshore areas to use them,what do you look for on the fish finder/gps that catches your attention the best?If I can get good at this pattern I believe I could catch fish that most people don,t even fish for around here.Anything you can give me on this subject will be anxiously anticipated.Thanks
