>>1428614>benefits of low profile casting reels>full sized traditional onestheyre smaller, lighter, cast better and commonly come in 100-200 sized they also hold less line. there are larger low pro reels 300-400-500 sized reels that hold much more line than their 100-200 cousins and are still considered low profile. And then theres round reels which depending on size you get (they too come in smaller and larger models) Overall There isnt much difference these days between the two except for weight, shape, cast-ability, more choices of ratio and much better drag power. they all perform much better than your common abu round reel.
