If versatility is your goal, Dobyns makes some of the most versatile rods out there. If you’re a fan of the Champ 734 you have, you could always get an Xtasy for the sensitivity boost.
I use my DRX755 for 3/8-1/2 jigs and chatterbaits with a trailer and it works very well. Soft tip for loading up, and great backbone for working slop. Without a trailer, going down to a 4 power might work better, however, you would lose some backbone working in the grass. I haven’t thrown 3/8 jigs without a trailer on the 755 but it is rated down to 3/8 so it should be fine on that rod as well
