I have two 734Cs and one 733C. I use the 734Cs for spinnerbaits, buzzbaits, swim jigs, chatterbaits, and have tried paddle tails. I use the 733C for Super Spooks, Sammy 115s & poppers (around vegetation), lipless crankbaits (vegetation). I definitely use the 734C more.
I originally bought one of each to find out which one I would prefer for spinnerbaits. I knew that I wanted the 734C for buzzbaits and the 733C for Super Spooks. I discovered that I liked the 734C better for spinnerbaits because it had the combination of a strong backbone yet a softer tip compared to other 4 power rods I've used, ie MBR844C GLX. The 733C is a great rod for spinnerbaits and I found that it cast 3/8 ouncers more easily, but I prefer a more powerful rod in part due to size of fish I catch as well as cover.
