A:
I wouldn't use a IMX or GLX for a top water rod. The rod I use for top water applications is the CBR783 Crankbait Series rods. I go with the 6'6" length as it allows me to walk the dog easier and it an all around better top water rod for me.
I like the action of the tip of this rod as I feel that on occasion if I set the hook too quickly it gives the baits the few milliseconds "I" need to keep me from jerking the bait away from the fish when I rookie one. The rod also has a ton of backbone so when you get into a large fish you have the backbone you need.
The rod is light and balanced which makes it a dream to fish with for extended periods of time.
