A couple of things to consider is whether you want it be a disc drag reel, or a click and pawl style reel. Some individuals go the classic reel route and they get a J.W. Young type reel to put on their rod for instance, and that would be click and pawl style. However, some like to go more modern and you have a wide variety depending on look, disc drag type, color, manufacturer and the list goes on and on. Couple of other things to consider is how much you are willing to spend, under $ 100, or perhaps between $ 100 to $ 300 for a reel. Also, if you plan on putting the reel, on a switch rod, some like to use a basic rule of thumb that the reel should be two sizes up from the weight of the switch rod. For instance if it is a six weight switch rod, you should put on an eight weight size reel to balance out the rod. Just my two cents on the matter.
