Been looking at either a casting setup or spinning for throwing super flukes and other weightless texas rigged soft plastics such as trick worms, finnesse worms etc.As well as a few 1/8-3/16oz weighted t-rigs like 4"-5" lizards and u-tales. Possibly dropshoting in shallow water around wood but thats not a necessity. The 702c will be matched with a 50e and not too sure on the spinning outfit (Never owned one). Whats yalls advice?

The 702c is only a fast action while the AVS68MXF is extra fast. I would use the extra fast action for all bottom contact baits.

If you've never had a spinning rig, I'd say go spinning here.

I have both rods you've mentioned by in the opposite versions. I've got a legend tournament topwater rod by St Croix. that's 6'8"MXF rod that I use for everything you've mentioned. And I've got aCurado 50E on it. I also use this rod for topwaters and jerkbaits. And the 702C I  have in the spinning rod version with a Daiwa Fuego reel. I use this rod almost always for dropshotting. And maybe for very small ripbaits, or smallish fluke type baits. I really like both setups but I think you would love the St Croix topwater rod, with your curado on it
