if you use a lot of deep crank's you better take a baitcasting combo.
but it's not necessary, its just better.
however like said before, you can catch fish on any rod. if youre a starter don't buy to much, later you will regret. cause you will know more about rods and reels, and you're gonna want you choosed an other rod, cause it's not perfect for what you will use it for, and finnaly you will know what's perfect for the use you will do with it, and buy again ...
