Shimano Crucial 7' MH for the bigger cranks. Works well with smaller cranks too. The M action Crucial is too limber for DD22s, the big Bomber Fat Frees, and the Strike King Series 6s -- you'll feel like the crank is throttling you. Its like that with any manufacturer if you don't have the correct action.

The 7' MH Crucial is a great all around rod. I throw all my cranks with it.
