Let me try and help. Dobyns crankbait rods are rated in crankbait powers and should not be confused with the fast action rods not specifically design to have moderate actions most anglers prefer in a treble hooked bait.
Note that the Champion cranking series all feature full cork grips. Only the Fury has the split grip.
The "glass" models are actually composite rods.
The 704CB Glass is a very moderate action model and is designed for smaller lighter baits. It is my least used model but when I fish finesse crankbaits on #8 this is the go to rod. It loads extremely easy. This, to me is the only model that would warrant the description of being " whippy. " It is very light and well balanced. I throw 1/8 oz. Speed Traps, SK 1.5 Shallow and 100 Bandits with it. I will use it for Normans Deep Tiny N's too.
The 704CB is in my opinion the best jerk bait rod in the Dobyns line up. Even though having a moderate action the tip is active and rebounds pretty fast. If I'm fishing 1.5 to 2.0 baits around rock and light vegetation this is a great rod. I also use it for poppers. The sweet spot on this rod is 3/8 oz but it will handle more. I also have the 684CB. Same features
The 705CB glass has tip and power. The tip is slightly slower but it shuts off in the middle third of the blank and will move big fish. I have no qualms fishing this rod around docks, big wood or heavy vegetation. I actually like this rod when I'm fishing Lipless baits like Rattle Traps, YZ Vibes and Drums for smallies. The rod is much lighter than my SR705R.
The 705CB is my actual square bill rod but it is much more versatile and makes a great heavy jerkbait rod, topwater rod and a super target spinnerbait rod when you are using 1/4 or 3/8 ounce baits around trees. This model is a bit quicker in it's action and is moderate enough to keep treble hook baits buttoned up. It still has ample power on the lower 60% of the blank to pressure bigger fish and move them away from cover. This rod works well for lipless baits and deeper divers similar to a Normans Deep Little N. Sensitivity is really good and the rod is balanced well. Most important, it loads nicely so casting effort is easy. I love it for wake baits.
Last, I have a 736CB Glass. I bought this rod expressly to throw chatterbaits but have found it to be a insane spinnerbait rod. I suppose I could throw magnum squarebills with it but I don't own any of 8.0 sizes.
I like moderate actions and the "glass feel." All my previous crankbait rods were Lamiglas. I can get that forgiving power in a graphite with my Dobyns and at a much lighter weight with a more comfortable handle and balance.
The model I would point you to is the Champion 705CB. I think it would be a win win for you. Good luck.
