Proper action and power for deep crankin rod?

[keithdog]

This question is very specific. If your looking for a crankbait specific rod for larger crankbaits like the DT16's, and DD22's, what would you consider the proper power and action built into the rod? I'm looking at both fiberglass and fiberglass/graphite blend rods made specifically for crankbaits for my large deep divers. I'll be probably going with a 7 foot rod. But I'm not sure if I should go with a MH or M power blank, and whether it should be a M or MF action taper? For large crankbaits, I would think a MH with a M or MF action would work well. But from what I have read, the pros often go with a M power rod even for their larger cranks. But I wonder if it is dependant on the composition of the rod.
