I'd snag the 7'2 MH/XF rod for your jigs. You can also use it for spinnerbaits, swim jigs, texas rigging and a lot of other things. Especially if you can toss treble hook presentations on your blackmax combo I would just get a set up that can do more than just cranks, top water, etc. They definitely require different rods. Also, if you are right handed, go ahead and snag either the G6 or G7.
If you don't decide to get one of those I would check out the Powell Endurance online at the fish ranger. I paired one of mine with a BPS PQ and I really like the combo. I'd recommend the 723c but the 703 and 704 are great rods as well
