I can not speak of other rods because I only use Denali rods .I know some people will think of course he uses them and endorses Denali because he is on their pro staff.
Before I signed a contract I researched the rods and the company .I would not endorse something I did not believe in. .I'm a local Pro with 50 plus years experience. There are other things to think about when buying a rod. Customer service and the integrity and honesty of the company.
There customer servicer at Denali is fantastic, The Owner Scott Estes will answer the phone and answer all your questions you may have and take his time and not rush you(how many large corporations do that). The National sales manger Mike Helton is the same way ,All of this means allot to me and I'm sure you as well. These big corporations who buy up all the good small companies are trying to cash in on the these companies reputation! What happens they, make the rod cheaper in construction get a big name pro to endorse them and it is all down hill from there. Look what happened to Allstar rods after Pure Ffishing bough them. Now you can not find a new Allstar rod. The same thing happened when Browning bough Lew's reels. If you are old enough to remember
Denali makes a great rod that will last you a long time and have people who will stand by them and they also have a life time warranty , There Jadewood rod For $99 is a great buy and compares to many rods that are higher in price..
I have been on my soap box a long time so I will get to the point. The 6'10" Kovert rod I assume you mean the crankbait rod is a great rod for Sq bills small to medium crankbaits, traps but I think is to stiff for a top water unless it's a buzz bait. The Michael Murphy rod is the best for TW and jerrkbaits and small to medium CB's in open water .If you are going to use allot of SQ' bills, small and med CB's in heavy cover stick with the 6'10" Kovert. You could use the Kovert for TW but you need to careful and play the fish as this is a stiff rod for top water .You could use mono with allot of stretch which be would helpful with using this rod for top water.
It all depends on what you would use it for. If you could afford both that's what I would do . Then you got it all covered .You need to think of rods like golf clubs. You would not use a putter for driving or vice versa. Hope this helps and does not confuse you.
