Sounds Ok, are they comfortable from a yaking position? Is their over kill I don't think so if its comfortable and not cumbersome, gearing in the reel may be more important.
I haven't seen one in person or read a review yet but their is a new line of Kayak rods by Okuma called Baidarka
, have a leash point made for being in a seated position, and they float, but no idea if its more gimmicky or quality.
I'm gonna try to explain this, but it may come out wrong, or maybe my thinking is just wrong. Back bone is good for setting the hook, not really needed or helpful in stopping a big fish from going where it wants to. The kayak acts as drag and helps you tire a fish, but it doesn't take much pull to move you. I have had 5 lbs. fish take me for a ride.
Say it takes 10lbs of pull to move you, you have 15lbs line and drag set to 11lbs., ok the fish won't take line but if it is pulling at 10lbs no matter how hard you pull back youre going for a ride. right?
