I am looking into buying a new fishing rod and the two options are either a 5′10″ rod or a longer 6′6″ rod, i usually just fish the detroit river and i do many different styles from casting to trolling to jigging and pretty much anything that’s working. but i would like to know what the advantages of getting the shorter rod would be and what the advantages of getting the longer rod would be, also please let me know any disadvantages either might have, they are the same brand same price same everything except for the length, both are even medium action. Thank you for helping me with this.
