So 3 casting rods from the old Mojo line to get started?
6'8 M/F- Topwater, jerkbait, finesse jigs/t-rigs. Could get away with throwing squarebills and lipless in a pinch.
7'1 MH/F- Can do all kinds of stuff with this rod. Jigs, swim jigs, Texas-rig, chatterbaits, spinnerbaits, buzzbaits, paddletail swimbaits.
7'4 H/F- Frog and flipping heavier cover.
Another great series of rods that are on the 'cheaper' end are the Ark Randall Tharp Honey Badger Series. They retail for $130, but with the new line coming out, these may be getting discounted soon. I think they punch higher than their price-point, and they look great as well. But you can't go wrong with the Mojo's, either.
